Two small CSS fixes:
1. Add background and reduced padding/avatar size to dashboard navbar.
We use that background already in a number of "secondary navbars", so it
fits.

src="ce5ebedc-e607-42c7-b7b4-b7a4c0ee68f2">
2. Fix padding on top of user settings and subscriptions, regressed by
https://github.com/go-gitea/gitea/pull/29922.
There is a small layout shift in when active tab changes. Notice how the
actions SVG is unstable:

This is because the active item with bold text is wider then the
inactive one. I have applied [this
trick](https://stackoverflow.com/a/32570813/808699) to prevent this
layout shift. It's only active inside `<overflow-menu>` because I wanted
to avoid changing HTML and doing it in regular JS would cause a flicker.
I don't expect us to introduce other similar menus without
`<overflow-menu>`, so that place is likely fine.

I also changed the weight from 500 to 600, slightly reduced horizontal
padding, merged some tab-bar related CSS rules and a added a small
margin below repo-header so it does not look so crammed against the
buttons on top.

The negative margin was suboptimal and presents a few unnecessary
challenges while styling the page. Remove it and add custom margin
values, which slightly changes the height a few things near the top of
the page as well:
15px less height of explore and login navbar:

15px reduced padding-top height of "user bar" and equal 4px padding
added:

1. Introduce a special "flex-items-block" for menu items, to align the
dropdown menu items
2. Simplify the "repo search" form
3. Add missing "TopicOnly" search option

Previously it was only partially styled, e.g. there was black text on
white background even in dark theme caused by fomantic styles.

Fomantic grey labels in the dashboard repo lists were showing original
fomantic colors, fixed that. Also slightly tweaked the light theme
colors so it uses same opacity values as dark theme.

- hide repo button text instead of icons in mobile view
- use same tab style as on explore and org 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.

1. Put the `"octicon-shield-lock"` into the flex container, then it
doesn't need a separate flex box
2. Remove some unnecessary `gt-df` helpers
3. Make `btn` button has the same flex behavior as `ui button`


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:

Also, this cleans up the related CSS vars:
- `--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.

Replace #26850
Major changes:
1. Remove all `has` selectors, it is still not supported by firefox.
Actually there could be some more general and clearer approaches
2. Remove `two-toggle-buttons`, the `.ui.buttons` just works well
3. Rewrite the `.ui.buttons` border styles, see the screenshots
4. Remove the "fine-tuning" paddings from the the flex children, they
could layout themselves well.




The old code used complex `if` blocks and strange HTML layouts.

This PR refactors the template code and remove legacy CSS styles. The UI
doesn't change much.


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.
Backtick syntax now works in repo description too. Also, I replaced the
CSS for this was a new single class, making it more flexible and not
dependent on a parent. Also, very slightly reduced font size from 16.8px
to 16px.

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.
## 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#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
Add `box-shadow` replacement to the `floating` dropdown variant as well,
which was missed in https://github.com/go-gitea/gitea/pull/26469. The
Fomantic style has `!important`, so this has to have too. Also made a
tiny adjustment to shadow color on dark theme.

Removes all dropdown and dimmer animations. Works everywhere as far as I
can tell, but need to give this thorough testing. Removes around 70kb
JS/CSS.
Note, I'm not 100% sure regarding the various callbacks, those will need
more investigation, but it appears to work nonetheless.
