Remove all Fomantic `inverted` variations, we are no using any of them.
This reduces the index CSS bundle by 98kB.

It causes not only one issue like #25221 (the footer width was also
affected by that change and was fixed some time ago)
The problem of "overflow: overlay" (#21850) is:
* It's not widely supported and is non-standard
https://caniuse.com/css-overflow-overlay
* It's not widely tested in Gitea (some standard layout like `ui
container + ui grid` may break it).
* The benefit seems smaller than the problems it brings.
So, I think it is good to revert it.
----
Let's leave enough time for testing and reviewing.

Fomantic brings a opinionated style that removed underline on mouse
hover which I think is important UX to have.
This re-enables the underline in the Fomantic config and fixes a few
cases where underline was deemed disruptive.
CSS-only tooltips suffer various issues with positioning and there was
only one single instance of them in the templates. Replace that instance
with a regular popup and exclude these `data-tooltip` styles from the
Fomantic build.
* Improve disabled styles for repo buttons
- Simplify disabled styling of label by matching for the disabled
attribute.
- Raise fomantic disabled opacity from .45 to .55 to for more contrast.
- Use CSS vars for basic button styles.
* restore clickability on label
* color tweaks and remove arc-green style
* slightly reduce button size
* consolidate vars
* also cover active class
* slightly more distinct active class

* CSS color variables, less bold font weight
- Define color variables for fully saturated colors and apply them where
it made sense
- Add background color helper classes
- Globally reduce bold font weight from 700 to 500
- Remove border from timeline icons
- Unify dropzone styling
- Various border style consolidations
* attempt to fix test
