Backport #24340 by @silverwind

Fixes https://github.com/go-gitea/gitea/issues/24321. By not setting
this meta tag, Safari will use body color for chrome and out-of-viewport
areas, which looks much better then static mismatching green.

As per
[MDN](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/meta/name/theme-color)
it's really only Apple browsers who still support this tag, most others
have dropped support.

Backport #23194

## TLDR

* Fix the broken page / broken image problem when click "Install"
* Fix the Password Hash Algorithm display problem for #22942
* Close #20089
* Close #23183
* Close #23184

## Details

### The broken page / broken image problem when clicking on "Install"
(Redirect failed after install - #23184)

Before: when clicking on "install", all new requests will fail, because the
server has been restarted. Users just see a broken page with broken
images, sometimes the server is not ready but the user would have been
redirect to "/user/login" page, then the users see a new broken page
(connection refused or something wrong ...)


After: only check InstallLock=true for necessary handlers, and sleep for
a while before restarting the server, then the browser has enough time
to load the "post-install" page. And there is a script to check whether
"/user/login" is ready, the user will only be redirected to the login
page when the server is ready.

### During new instance setup fill 'Gitea Base URL' with
window.location.origin - #20089

If the "app_url" input contains `localhost` (the default value from
config), use current window's location href as the `app_url` (aka
ROOT_URL)


### Fix the Password Hash Algorithm display problem for "Provide the
ability to set password hash algorithm parameters #22942"

Before: the UI shows `pbkdf2$50000$50`

Backport #23059

This PR is trying to add accessibility to the menu as mentioned in
#23053 so the menu can be accessed using keyboard (A quick demo is added
below), with a reference to
[PR2612](https://github.com/go-gitea/gitea/pull/22612). The goal is to
make the menu accessible merely using keyboard like shown below. And
this PR might need confirmation from developers using screen readers.

This PR follows:
* #21986
* #22831

This PR also introduce customized HTML elements, which would also help
problems like:
* #17760
* #21429
* #21440

With customized HTML elements, there won't be any load-search-replace
operations, and it can avoid page flicking (which @silverwind cares a
lot).

# FAQ

## Why the component has the prefix?

As usual, I would strongly suggest to add prefixes for our own/private
names. The dedicated prefix will avoid conflicts in the future, and it
makes it easier to introduce various 3rd components, like GitHub's
`relative-time` component. If there is no prefix, it's impossible to
introduce another public component with the same name in the future.

## Why the `custcomp.js` is loaded before HTML body? The `index.js` is
after HTML body.

Customized components must be registered before the content loading.
Otherwise there would be still some flicking.

`custcomp.js` should have its own dependencies and should be very light,
so it won't affect the page loading time too much.

## Why use `data-url` attribute but not use the `textContent`?

According to the standard, the `connectedCallback` occurs on the
tag-opening moment. The element's children are not ready yet.

## Why not use `{{.GuessCurrentOrigin $.ctx ...}}` to let backend decide
the absolute URL?

It's difficult for backend to guess the correct protocol(scheme)
correctly with zero configuration. Generating the absolute URL from
frontend can guarantee that the URL is 100% correct -- since the user is
visiting it.

To avoid duplicated load of the same data in an HTTP request, we can set
a context cache to do that. i.e. Some pages may load a user from a
database with the same id in different areas on the same page. But the
code is hidden in two different deep logic. How should we share the
user? As a result of this PR, now if both entry functions accept
`context.Context` as the first parameter and we just need to refactor
`GetUserByID` to reuse the user from the context cache. Then it will not
be loaded twice on an HTTP request.

But of course, sometimes we would like to reload an object from the
database, that's why `RemoveContextData` is also exposed.

The core context cache is here. It defines a new context
```go
type cacheContext struct {
	ctx  context.Context
	data map[any]map[any]any
        lock sync.RWMutex
}

var cacheContextKey = struct{}{}

func WithCacheContext(ctx context.Context) context.Context {
	return context.WithValue(ctx, cacheContextKey, &cacheContext{
		ctx:  ctx,
		data: make(map[any]map[any]any),
	})
}
```

Then you can use the below 4 methods to read/write/del the data within
the same context.

```go
func GetContextData(ctx context.Context, tp, key any) any
func SetContextData(ctx context.Context, tp, key, value any)
func RemoveContextData(ctx context.Context, tp, key any)
func GetWithContextCache[T any](ctx context.Context, cacheGroupKey string, cacheTargetID any, f func() (T, error)) (T, error)
```

Then let's take a look at how `system.GetString` implement it.

```go
func GetSetting(ctx context.Context, key string) (string, error) {
	return cache.GetWithContextCache(ctx, contextCacheKey, key, func() (string, error) {
		return cache.GetString(genSettingCacheKey(key), func() (string, error) {
			res, err := GetSettingNoCache(ctx, key)
			if err != nil {
				return "", err
			}
			return res.SettingValue, nil
		})
	})
}
```

First, it will check if context data include the setting object with the
key. If not, it will query from the global cache which may be memory or
a Redis cache. If not, it will get the object from the database. In the
end, if the object gets from the global cache or database, it will be
set into the context cache.

An object stored in the context cache will only be destroyed after the
context disappeared.

As discussed in #22847 the helpers in helpers.less need to have a
separate prefix as they are causing conflicts with fomantic styles

This will allow us to have the `.gt-hidden { display:none !important; }`
style that is needed to for the reverted PR.

Of note in doing this I have noticed that there was already a conflict
with at least one chroma style which this PR now avoids.

I've also added in the `gt-hidden` style that matches the tailwind one
and switched the code that needed it to use that.

In some cases, the loading failure of `index.js` is not related to the
ROOT_URL directly, ex: https://gitea.com/gitea/helm-chart/issues/392

If the user's reversed proxy is mis-configured:
`http://public-domain/gitea/xxx` -> `http://gitea:3000/gitea/xxx`, it
also causes the loading failure.

So this PR removes the ROOT_URL related tip from the error message.

If you don't use the `auto` theme as the default, the `<html>` tag has
`theme-auto` as it's class when users are logged out. This PR changes it
to use the correct theme class for the default theme when logged out.

Fix #22286 

When timetracking is disabled, the stop watch top bar icon should be
hidden.
When the stop watch recording popup, it should be allowed to hide with
some operation. Now click any place on this page will hide the popup
window.

Replace `active{{end}} item` with `active{{end}} item`.

Keep the pages of the navigation in the center

This should solve the main problem of dynamic assets getting stale after
a version upgrade. Everything not affected will use query-string based
cache busting, which includes files loaded via HTML or worker scripts.

Previous solution that re-purposed the 'hide' class by making it
`!important` had various unintended side-effects where jQuery .show() was
not able to outweight it. Use a separate class to prevent these
interactions.

- replace fomantic popup module with tippy.js
- fix chaining and add comment
- add 100ms delay to tooltips
- stopwatch improvments, raise default maxWidth
- update web_src/js/features/common-global.js
- use type=submit instead of js

Introduce a separate .eslintrc in the Vue components folder to
selectively enable vue-eslint-parser there, so that the rest of the
files can use eslint's core parser which can deal with hashbangs.

The fact that the eslint-disable comments worked in HTML was a
unintended side-effect of the files being parsed via vue-eslint-parser,
so I had to disable the parsing of these files in .eslintrc.yaml to make
it work, and finally decided to remove eslint-plugin-html as it causes
more issues than it solves.

Unfortunately there is a bug in #20108 where the translation call was
not updated to use `.locale` from `.i18n`.

This PR updates the template to use `.locale`.

The use of `m-4 text black` for the notification bell results in this
icon being shifted upwards. Instead we should use the `item` class but
adjust `not-mobile` and `mobile-only` to make their `display: none`
settings `!important`.

(As an aside: This is probably one of the only times we should use
`!important` in our less files and the rest should be avoided or
removed.)

The recommended way is to use the name of the organisation followed
by "logo". however, since this is my first contribution, I am not
entirely sure, whether this is the best approach here.

The organisation is different from the organisation you can create as
part of the application. Instead, it is more related to the site
hosting the instance. Plus, I don't know how to best handle it when
the logo image is swapped out. Therefore, I use plain "Logo" and hope
that the person visiting the site has enough context.

Neiter `<meta>` nor `<link>` require a closing slash at the end in HTML,

* By default force vertical tabs on mobile

- While experimenting with using vertical tabs instead of horizontal
tabs on gitea for a better mobile experience, I made a recent
PR(https://github.com/go-gitea/gitea/pull/19468) in order to see if
there was any objections to this new behavior for the repo headers(one
of the most annoying horizontal tabs). This PR had no objections and
even a user commenting that this change is brilliant.
- This PR now improves upon the previous PR by making this the de-facto
behavior for all menu's on mobile. The only exemption is the navbar
which also uses the menu but caught some layout errors with the changes.

* ROOT_URL issues: some users did wrong to there app.ini config, then:
    * The assets can not be loaded (AppSubUrl != "" and users try to access http://host:3000/)
    *The ROOT_URL is wrong, then many URLs in Gitea are broken.
Now Gitea show enough information to users.

* JavaScript error issues, there are many users affected by JavaScript errors, some are caused by frontend bugs, some are caused by broken customized templates. If these JS errors can be found at first time, then maintainers do not need to ask about how bug occurs again and again.

* Some people like to modify the `head.tmpl`, so we separate the script part to `head_script.tmpl`, then it's much safer.

* use specialized CSS class "js-global-error", end users still have a chance to hide error messages by customized CSS styles.

The last PR about clone buttons introduced an JS error when visiting an empty repo page:
* https://github.com/go-gitea/gitea/pull/19028
* `Uncaught ReferenceError: isSSH is not defined`, because the variables are scoped and doesn't share between sub templates.

This:
1. Simplify `templates/repo/clone_buttons.tmpl` and make code clear
2. Move most JS code into `initRepoCloneLink`
3. Remove unused `CloneLink.Git`
4. Remove `ctx.Data["DisableSSH"] / ctx.Data["ExposeAnonSSH"] / ctx.Data["DisableHTTP"]`, and only set them when is is needed (eg: deploy keys / ssh keys)
5. Introduce `Data["CloneButton*"]` to provide data for clone buttons and links
6. Introduce `Data["RepoCloneLink"]` for the repo clone link (not the wiki)
7. Remove most `ctx.Data["PageIsWiki"]` because it has been set in the `/wiki` middleware
8. Remove incorrect `quickstart` class in `migrating.tmpl`

This PR mainly helps maintainers to save time from asking the issue reporters to get the correct version.

There are so many reporters that have difficulty to get the correct Gitea version. Some of they just report Go version.

The Go version doesn't help debug except in very limited circumstances. Instead, there is a new link on the Gitea version, the link is for the admin/config page which shows all version information, including Gitea, Go, Git, it could help more.
