The WIP prefix toggling link on the sidebar only supported toggling
the *first* prefix specified in
`[repository.pullrequest].WORK_IN_PROGRESS_PREFIXES`. If the pull
request had a title with any other prefix, the first prefix listed in
the config was added (and then removed on toggling it off).
This little change makes all of the prefixes available for the
JavaScript function that does the toggling, and changes said function to
find the used prefix first, and toggle that.
When adding the prefix, it will still default to adding the first one
listed in the configuration, but it will happily remove any others if
those are present.

On repo settings page, there id `repo_name` was used 5 times on the same
page, some in modal and such. I think we are better off just
auto-generating these IDs in the future so that labels link up with
their form element.
Ideally this id generation would be done in backend in a subtemplate,
but seeing that we already have similar JS patches for checkboxes, I
took the easy path for now.
I also checked that these `#repo_name` were not in use in JS and the
only case where this id appears in JS is on the migration page where
it's still there.

Get rid of one more jQuery dependant and have a nicer color picker as
well.
Now there is only a single global color picker init because that is all
that's necessary because the elements are present on the page when the
init code runs. The init is slightly weird because the module only takes
a selector instead of DOM elements directly.
The label modals now also perform form validation because previously it
was possible to trigger a 500 error `Color cannot be empty.` by clearing
out the color value on labels.

The recent refactor imported from Gitea made the Fork counter/button in
the repo header appear as icon only on mobile, but left the Star & Watch
buttons unchanged, so they appeared with text. That resulted in the
mobile view looking a bit awkward, with half the widgets (rss & fork) as
icon-only, while the other half (star & watch) with both icon and text.
This changes the other two in the same way: to appear without text on
mobile.

entire media query.
Migrate `gt-font-*` to `tw-text-*` All tailwind-original class names are
also available and render like they would with 16px root font size.
We currently have root font size at 14px, but I would like to eventually
migrate us to 16px so that the tailwind docs apply to us unchangend and
because 16px is the recommended root font size for web pages in general.
Also the number 16 is much better dividable than 14 so will result in
more integers.

Repositories displaying an "Add more..." tab on the header is a neat way
to let people discover they can enable more units. However, displaying
it all the time for repository owners, even when they deliberately do
not want to enable more units gets noisy very fast.
As such, this patch introduces a new setting which lets people disable

The modal was broken in two ways:
- On small screens, the input box was partially hanging outside the
modal. Fixed with flexbox and increased modal width.
- The clipboard copy was not working because the modal had both
`data-clipboard-text` and `data-clipboard-target`, while we only support
one of those. Made a small tweak in clipboard as well so that it will
still fall back to target if text is empty.

Refactor the webhook logic, to have the type-dependent processing happen
only in one place.
---
1. An event happens
2. It is pre-processed (depending on the webhook type) and its body is
added to a task queue
3. When the task is processed, some more logic (depending on the webhook
type as well) is applied to make an HTTP request
This means that webhook-type dependant logic is needed in step 2 and 3.
This is cumbersome and brittle to maintain.
Updated webhook flow with this PR:
1. An event happens
2. It is stored as-is and added to a task queue
3. When the task is processed, the event is processed (depending on the
webhook type) to make an HTTP request
So the only webhook-type dependent logic happens in one place (step 3)
which should be much more robust.
- the raw event must be stored in the hooktask (until now, the
pre-processed body was stored)
- to ensure that previous hooktasks are correctly sent, a
`payload_version` is added (version 1: the body has already been
pre-process / version 2: the body is the raw event)
So future webhook additions will only have to deal with creating an
http.Request based on the raw event (no need to adjust the code in
multiple places, like currently).
Moreover since this processing happens when fetching from the task
queue, it ensures that the queuing of new events (upon a `git push` for
instance) does not get slowed down by a slow webhook.
As a concrete example, the PR #19307 for custom webhooks, should be
substantially smaller:
- no need to change `services/webhook/deliver.go`
- minimal change in `services/webhook/webhook.go` (add the new webhook
to the map)
- no need to change all the individual webhook files (since with this
refactor the `*webhook_model.Webhook` is provided as argument)

Before this change, if we had more than 200 entries being deferred in
loading, the entire table would get replaced thus losing any event
listeners attached to the elements within the table, such as the elipsis
button and commit list with tippy.
With this change we remove the previous javascript code that replaced
the table and use htmx to replace the table.
htmx attributes added:
- `hx-indicator="tr.notready td.message span"`: attach the loading
spinner to the files whose last commit is still being loaded
- `hx-trigger="load"` trigger the request-replace behavior as soon as
possible
- `hx-swap="morph"`: use the idiomorph morphing algorithm, this is the
thing that makes it so the elipsis button event listener is kept during
the replacement, fixing the bug because we don't actually replace the
table, only modifying it
- `hx-post="{{.LastCommitLoaderURL}}"`: make a post request to this url
to get the table with all of the commit information
As part of this change I removed the handling of partial replacement in
the case we have less than 200 "not ready" files. The first reason is
that I couldn't make htmx replace only a subset of returned elements,
the second reason is that we have a cache implemented in the backend
already so the only cost added is that we query the cache a few times
(which is sure to be populated due to the initial request), and the last
reason is that since the last refactor of this functionality that
removed jQuery we don't properly send the "not ready" entries as the
backend expects `FormData` with `f[]` and we send a JSON with `f` so we
always query for all rows anyway.

3. Assign rendered content to text field, for example: `r.Note =
rendered content` in web/repo/release.go
4. (possible) Incorrectly calling `{{Str2html
.PackageDescriptor.Metadata.ReleaseNotes}}` in
package/content/nuget.tmpl, I guess the name Str2html misleads
developers to use it to "render string to html", but it only sanitizes.
if ReleaseNotes really contains HTML, then this is not a problem.

this in the future.

Some specific events on Gitlab issues and merge requests are stored
separately from comments as "resource state events". With this change,
all relevant resource state events are downloaded during issue and merge
request migration, and converted to comments.
This PR also updates the template used to render comments to add support
for migrated comments of these types.

This partially reverts c41b2c73ef: for the
sake of consistency, the title of a release should always be a link,
whether it's a tag-only release or not.

- When a user goes opens a symlink file in Forgejo, the file would be
rendered with the path of the symlink as content.
- Add a button that is shown when the user opens a *valid* symlink file,
which means that the symlink must have an valid path to an existent
file and after 999 follows isn't a symlink anymore.
- Return the relative path from the `FollowLink` functions, because Git
really doesn't want to tell where an file is located based on the blob ID.
- Adds integration tests.
