Reorder blocks in vue SFCs (#26874)
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.

Remove "TODO" tasks from CSS file (#26835)
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.

Remove joinPaths function (#26833)
Extract from https://github.com/go-gitea/gitea/pull/25940.

`assetUrlPrefix` is guaranteed to not contain trailing slashes, making
this function unneeded.

Remove polluted .ui.right (#26825)
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.

Fix Uint8Array comparisons and update vitest (#26805)
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.

Fix incorrect "tabindex" attributes (#26733)
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"
4. Some tabindex values are incorrect (eg: `new_form.tmpl`), so remove them

Simplify helper CSS classes and avoid abuse (#26728)
Removed CSS helper classes (some of them are not useful while some of
them are abused often)

* `gt-db`: in most cases it could be replaced by `gt-df` and the flex
layout should be encouraged. Other cases: either it does need the
`gt-df` (eg: by using `div` directly) or it is an abuse (eg: the warning
message in a form)
* `gt-di`: it doesn't seem useful, or it could be replaced by `gt-dib`
in most cases.
* `gt-dif`: not useful, it could be replaced by `flex-text-inline` or
`gt-df`
* `gt-js`: never used
* All `<i class="icon gt-df gt-ac gt-jc">` could be written as `<i
class="icon">`

it was tiny and on fast machines only visible for a fraction of a
second):

Also, heatmap container does not resize any more after loading now and
previous duplicate id `user-heatmap` is gone.

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.

Use "small-loading-icon" insead of "btn-octicon is-loading" (#26710)
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.

In current design, the clickable area is too small, and it is hard to
find the correct clickable area as the area with background color (div
with class name `job-brief-item selected`) is bigger than it.

Allow to archive labels (#26478)
## 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.

## Screenshots

Refactor project templates (#26448)
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 😆

Don't autosize textarea in diff view (#26233)
Resizing the comment editor can be a very expensive operation because it
triggers page reflows, which on large PRs can take upwards of seconds to
complete. Disable this mechanism on the diff page only where we know
that the page can get large.

Fixes https://github.com/go-gitea/gitea/issues/26201 for the textarea
editor.

I don't think this can be fixed for EasyMDE because as far as I can
tell, it exposes no option to disable this resizing.

Add commits dropdown in PR files view and allow commit by commit review (#25528)
This PR adds a new dropdown to select a commit or a commit range
(shift-click like github) of a Pull Request.
After selection of a commit only the changes of this commit will be shown.
When selecting a range of commits the diff of this range is shown.

This allows to review a PR commit by commit or by viewing only commit ranges.
The "Show changes since your last review" mechanism github uses is implemented, too.
When reviewing a single commit or a commit range the "Viewed" functionality is disabled.

## Screenshots

Show branches and tags that contain a commit (#25180)
Now, you can see for a commit which existing branches and tags contain it.
You first have to click on the `load branches and tags` button, they are not preloaded by default.
All branches and tags are ordered descending by creation date.
You can even see without much hassle if the given commit is already part of the default branch.

Closes #25152

Use frontend fetch for branch dropdown component (#25719)
- Send request to get branch/tag list, use loading icon when waiting for
response.
- Only fetch when the first time branch/tag list shows.
- For backend, removed assignment to `ctx.Data["Branches"]` and
`ctx.Data["Tags"]` from `context/repo.go` and passed these data wherever
needed.
- Changed some `v-if` to `v-show` and used native `svg` as mentioned in
https://github.com/go-gitea/gitea/pull/25719#issuecomment-1631712757 to
improve perfomance when there are a lot of branches.
- Places Used the dropdown component:

to more dropdown menus.

Actions Artifacts support uploading multiple files and directories (#24874)
current actions artifacts implementation only support single file
artifact. To support multiple files uploading, it needs:

- 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
to `{path}/{artifact-path}`.
- in repo action view, it provides zip download link in artifacts list
in summary page, no matter this artifact contains single or multiple
files.

Show the mismatched ROOT_URL warning on the sign-in page if OAuth2 is enabled (#25947)
Since OAuth2 will callback the root URL, if the user starts signing in
from a wrong host, Gitea will return 500 because it cannot find the
session.
