The overflow menu button was incorrectly included in the measurement of
the width of the items. As a result, it could get stuck in a loop
alternating between different measurements as the button appears and
disappears.
Fixes https://github.com/go-gitea/gitea/issues/30721 and overhauls the
stopwatch. Time is now shown inside the "dot" icon and on both mobile
and desktop. All rendering is now done by `<relative-time>`, the
`pretty-ms` dependency is dropped.

Note for tippy:
Previously, tippy instances defaulted to "menu" theme, but that theme is
really only meant for `.ui.menu`, so it was not optimal for the
stopwatch popover.
This introduces a unopinionated `default` theme that has no padding and
should be suitable for all content. I reviewed all existing uses and
explicitely set the desired `theme` on all of them.
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.
