In the commit 5a56f9699c (3.) the min-height was applied to all wiki
elements. This resulted in huge blank spaces when viewing the wiki.
This fixes this by only applying the min-height to the preview when
editing.

When the form is going to be submitted, add the "is-loading" class to
show an indicator and avoid user UI events.
When the request finishes (success / error), remove the "is-loading"
class to make user can interact the UI.
To improve maintainability, this PR:
1. Rename `web_src/js/modules/aria` to `web_src/js/modules/fomantic`
(the code there are all for aria of fomantic)
2. Move api/transition related code to
`web_src/js/modules/fomantic/api.js` and
`web_src/js/modules/fomantic/transition.js`
No logic is changed.
* Show checkout instructions also when there is no permission to push,
for anyone who wants to locally test the changes.
* First checkout the branch exactly as is, without immediately having to
solve merge conflicts. Leave this to the merge step, since it's often
convenient to test a change without worrying about this.
* Use `git fetch -u`, so an existing local branch is updated when
re-testing the same pull request. But not the more risky `git fetch -f`
in to handle force pushes, as we don't want to accidentally overwrite
important local changes.
* Show different merge command depending on the chosen merge style,
interactively updated.
When hitting the `enter` key to create a new project column, the request
is sent twice because the `submit` event and `key up` event are both
triggered.
Probably a better solution is to rewrite these parts of the code to
avoid using native jQuery but reuse the `form-fetch-action` class. But
it's beyond my ability.
1. Do not show temporary tooltips that are triggered from within
dropdowns. Previously this resulted in the tooltip being stuck to
top-left of the page like seen on issue comment URL copy. I could not
figure out any tippy options that prevent this, so I think it's better
to just not show it.
1. Refactor `initGlobalCopyToClipboardListener` so that it does not run
a often useless `document.querySelector` on every click, make
`data-clipboard-text-type` work with `data-clipboard-target`. No use in
current code base but still good to have. Finally some minor code
cleanup in the function.
Point 1 is for this copy button:

1. Dropzone attachment removal, pretty simple replacement
2. Image diff: The previous code fetched every image twice, once via
`img[src]` and once via `$.ajax`. Now it's only fetched once and a
second time only when necessary. The image diff code was partially
rewritten.

This patch adds a hover background for the wiki row in wiki list page,
which make its behavior more close to repo's file list page.
This patch also make the wiki-git-entry visible on the row is hovered
instead of the cel, so users won't be confused since the 'grid' is not
visible from the web page.

Part of https://github.com/go-gitea/gitea/issues/27097:
- `gitea` theme is renamed to `gitea-light`
- `arc-green` theme is renamed to `gitea-dark`
- `auto` theme is renamed to `gitea-auto`
I put both themes in separate CSS files, removing all colors from the
base CSS. Existing users will be migrated to the new theme names. The
dark theme recolor will follow in a separate PR.
## ⚠️ BREAKING ⚠️
1. If there are existing custom themes with the names `gitea-light` or
`gitea-dark`, rename them before this upgrade and update the `theme`
column in the `user` table for each affected user.
2. The theme in `<html>` has moved from `class="theme-name"` to
`data-theme="name"`, existing customizations that depend on should be
updated.

This PR reduces the complexity of the system setting system.
It only needs one line to introduce a new option, and the option can be
used anywhere out-of-box.
It is still high-performant (and more performant) because the config
values are cached in the config system.
Currently, checkboxes are positioned as absolute. This positioning
causes the input to overlay an element that has been floated within the
editor. Floated elements are useful if you want your text to wrap around
this element. This PR fixes the overlaying of checkboxes by removing the
absolute positioning, updating the `ul` padding, and
displaying`.task-list-item` `flex` to ensure inputs and the associated
label are on the same line.

The `.new-menu` was using a pseudo-element based fade-out effect.
Replace this with a more modern mask-based effect which in this case
required a child element to avoid fading out the background as well, so
I applied it to child `new-menu-inner` which was present on all these
menus except explore where I added it.
There is no visual difference except that the items on the explore page
have no `gap` between them any longer, making it consistent with other
menus. Before and after:

- `--color-header-wrapper-transparent` is removed, no longer needed
- `--color-header-wrapper` is defined in base theme as well, was
previously unset and therefor transparent.

WIP because:
- [x] Some calls set a `content-type` but send no body, can likely
remove the header
- [x] Need to check whether `charset=utf-8` has any significance on the
webauthn calls, I assume not as it is the default for json content.
- [x] Maybe `no-restricted-globals` is better for eslint, but will
require a lot of duplication in the yaml or moving eslint config to a
`.js` extension.
- [x] Maybe export `request` as `fetch`, shadowing the global.
1. Introduce lightweight `fetch` wrapper functions that automatically
sets csfr token, content-type and use it in `RepoActionView.vue`.
2. Fix a specific issue on `RepoActionView.vue` where a fetch network
error is shortly visible during page reload sometimes. It can be
reproduced by F5-in in quick succession on the actions view page and was
also producing a red error box on the page.
Once approved, we can replace all current `fetch` uses in UI with this
in another PR.

Before:
* The layout is quite complex
* The UI flickers when switch the stats (https://try.gitea.io/)
After:
* Simplify the code
* The UI doesn't flicker
Align everything with a new layout.
* Use "baseline" for some special elements, the "flex-item-icon" is for
the issue list only at the moment and I think it should be general
enough now (but not using "flex-item-leading" anymore in this case).
* Make the labels stretch themselves.
1. There is already `gt-ac`, so no need to introduce `flex-item-center`
2. The `flex-item-baseline` and `.flex-item-icon svg { margin-top: 1px
}` seem to be a tricky patch, they don't resolve the root problem, and
still cause misalignment in some cases.
* The root problem is: the "icon" needs to align with the sibling
"title"
* So, make the "icon" and the "title" both have the same height
3. `flex-text-inline` could only be used if the element is really
"inline", otherwise its `vertical-align` would make the box size change.
In most cases, `flex-text-block` is good enough.

1. In many cases, the `flex-list` has previous and next `gt-hidden`
siblings, so relax the CSS selector to remove all ".segument .flex-list"
paddings.
2. Make the "Add key" button can toggle
3. Move help message into the related segment(panel). Otherwise users
would misread the message, eg: the SSH help seemed for GPG because they
are so near
4. Move modal element into the segment element, otherwise it affects the
layout
The changes for "commit-body" in #26877 are not ideal.
The reason is: the "commit-body" is usually a `<pre>`, it has default
margins. In most cases, we do not need that large margin. So, this PR
introduces a general but small margin for all "commit-body" elements.
Then these `gt-m-0` could be removed.
The `:not` selector is not needed, because the `.timeline-item` selector
is already clear enough.
The [recommended order](https://vuejs.org/guide/scaling-up/sfc.html) for
SFC blocks is script -> template -> style, which we were violating
because template and script were swapped. I do find script first also
easier to read because the imports are on top, letting me immideatly see
a component's dependencies.
This is a pure cut-paste refactor with some removal of some empty lines.

1. Use `gt-invisible` instead of `invisible`.
2. Use `gt-word-break` instead of `dont-break-out` (there is a slight
different "hyphens", but I think it won't affect too much since it is
only used for the "full name").
3. Remove `.small.button:has(svg)` , now our buttons could layout SVG
correctly, and actually I didn't see this CSS class is used in code.
This PR implements a proposal to clean up the admin users table by

details page
- show if user is instance administrator as a label instead of a
separate column
- separate explore users template into a page- and a shared one, to make
it possible to use it on the user details page
- fix issue where there was no margin between alert message and
following content on admin pages

Each change is tested manually line by line. There are too many changes
so I can't share dozens of screenshots.
In short:
1. `ui right` could be still used in `ui top attached header`, because
there is a special case.
2. A lot of `ui right` are just no-op, so they can be removed safely.
3. Some of the `ui right` should be replaced by `gt-float-right` (to
avoid breaking, leave them to the future).
4. A few of the `ui right` could be rewritten by flex.
Corollary to #26775:
All selectors I found that are actually used and not necessarily present
in the current code have been copied to `web_src/css/base.css`.
Everything else should be a clean removal.
Compare those `Uint8Array` via conversion to Array which are properly
comparable, so that we don't have to worry about whether `TextEncoder`
and `UInt8Array` from the environment are compatible or not.

Replace #26761
It's better to keep children elements simple, and let parent containers
layout the necessary padding/margin.
The old `not(:last-child)` and `.flex-item + .flex-item` are not easy to
maintain (for example, what if the developer would like to use a "tiny
height" item?)
The old approach also makes some UI look strange because the first item
doesn't have proper padding-top.
In this PR, we just simply use `.flex-item { padding: ... }`:
* Developers could manually set the item height they want easily
* It's easier to make it work with various containers -- with padding
(`ui segment`) and without padding (`div`)
And added more samples/examples.

## Changes
- no more hardcoded `border-radius`es (apart from `0`)
- no more value inconsistencies
- no more guessing what pixel value you should use
- two new variables:
- `--border-radius-medium` (for elements where the normal border radius
does not suffice)
- `--border-radius-circle` (for displaying circles)

Fix#26731
Almost all "tabindex" in code are incorrect.
1. All "input/button" by default are focusable, so no need to use "tabindex=0"
2. All "div/span" by default are not focusable, so no need to use "tabindex=-1"
3. All "dropdown" are focusable by framework, so no need to use "tabindex"

Adds
[eslint-plugin-vue-scoped-css](https://github.com/future-architect/eslint-plugin-vue-scoped-css)
and fixes discovered issues which are:
- 1 unused selector
- 3 selectors with `.full.height` parent in a `<style scoped>` block so
the rule could not find the parent. Move these into the unscoped block
instead. They worked before and after.
Focus the editor when clicking the "Write" tab. Works for both Textarea
and EasyMDE. Does for some reason not work without the
`requestAnimationFrame`.
The "btn-octicon is-loading" was introduced by #21842 , it is only used
by the "Copy Content" button, but the "btn-octicon" selector would
affect too many uncertain elements.
Now there is a general "small-loading-icon" class, so the "btn-octicon
is-loading" could be removed.
1. Use `is-loading` instead of `ui loader`
2. Introduce class name `image-diff-tabs`, instead of searching `gt-hidden`, which is fragile
3. Align the UI elements, see the screenshots.
Now Gitea exposes unhandled promise rejection messages as error message on the UI.
The "comment form" was quite unclear before, so it should be handled more gracefully to avoid such error.
Fix#26617
1. Separate the "flex-list" examples into a dedicated template, and add some more examples
2. Use `flex-basis` instead of `flex-shrink` for `flex-item-trailing`, to avoid wrapping the texts too aggressively
3. Some `flex-wrap: wrap;` are removed

## Archived labels
This adds the structure to allow for archived labels.
Archived labels are, just like closed milestones or projects, a medium to hide information without deleting it.
It is especially useful if there are outdated labels that should no longer be used without deleting the label entirely.
## Changes
1. UI and API have been equipped with the support to mark a label as archived
2. The time when a label has been archived will be stored in the DB
## Outsourced for the future
There's no special handling for archived labels at the moment.
This will be done in the future.

Previously, the tooltip for this button was only shown after opening and
closing it once because it was only set after the server response, now
it shows before opening it.
This PR refactors a bunch of projects-related code, mostly the
templates.
The following things were done:
- rename boards to columns in frontend code
- use the new `ctx.Locale.Tr` method
- cleanup template, remove useless newlines, classes, comments
- merge org-/user and repo level project template together
- move "new column" button into project toolbar
- move issue card (shared by projects and pinned issues) to shared
template, remove useless duplicated styles
- add search function to projects (to make the layout more similar to
milestones list where it is inherited from 😆)
- maybe more changes I forgot I've done 😆Closes#24893

- save each file to each db record with same run-id, same artifact-name
and proper artifact-path
- need change artifact uploading url without artifact-id, multiple files
creates multiple artifact-ids
- support `path` in download-artifact action. artifact should download

This commit removes the hard-coded height of 500px, using that as a
max-height instead. The height of items in the dropdown menu, assuming a
default font size of 16px, is 36px, so the old CSS would cause overly
large dropdown menus in instances where less than 14 languages are
offered.

Move `public/*` to `public/assets/*`
Some old PRs (like #15219) introduced inconsistent directory system.
For example: why the local directory "public" is accessed by
`http://site/assets`? How to serve the ".well-known" files properly in
the public directory?
For convention rules, the "public" directory is widely used for the
website's root directory. It shouldn't be an exception for Gitea.
So, this PR makes the things consistent:
* `http://site/assets/foo` means `{CustomPath}/public/assets/foo`.
* `{CustomPath}/public/.well-known` and `{CustomPath}/public/robots.txt`
can be used in the future.
This PR is also a prerequisite for a clear solution for:
* #21942
* #25892
* discourse.gitea.io: [.well-known path serving custom files behind
proxy?](https://discourse.gitea.io/t/well-known-path-serving-custom-files-behind-proxy/5445/1)
This PR is breaking for users who have custom "public" files (CSS/JS).
After getting approvals, I will update the documents.

Previously, `sortablejs` was imported twice, once synchronously and once

Use a real button and add an aria-label.
Additionally, show the button whenever it is focused.

the "install page" also writes the environment variables to the config
file.
And, to make things clear, there are enough messages on the UI to tell
users what will happen.
There are some necessary/related changes to `environment-to-ini.go`:
* The "--clear" flag is removed and it was incorrectly written there.
The "clear" operation should be done if INSTALL_LOCK=true
* The "--prefix" flag is removed because it's never used, never
documented and it only causes inconsistent behavior.

Fix#25627
1. `ctx.Data["Link"]` should use relative URL but not AppURL
2. The `data-params` is incorrect because it doesn't contain "page". JS
can simply use "window.location.search" to construct the AJAX URL
3. The `data-xxx` and `id` in notification_subscriptions.tmpl were
copied&pasted, they don't have affect.
Monaco can not deal with color formats other than 6-digit hex, so we
convert the colors for it via new
[`tinycolor2`](https://github.com/bgrins/TinyColor) dependency (5kB
minzipped).
Also, with the addition of the module, we can replace the existing
`hexToRGBColor` usage, I verified it is compatible with the current
tests before removing the function.

This will prevent the most common cases of SVG shrinking because lack of
space. I evaluated multiple options and this seems to be the one with
the least impact in size and processing cost, so I went with it.
Unfortunately, CSS can not dynamically convert `16` obtained from
`attr()` to `16px`, or else a generic solution for all sizes would have
been possible. But a solution is [in
sight](https://developer.mozilla.org/en-US/docs/Web/CSS/attr#type-or-unit)
with `attr(width px)` but no browser supports it currently.
