Fix all rounded borders, change affected tab menus to pills (#30707)

Fixes https://github.com/go-gitea/gitea/issues/30673, all 23 issues.
Notes:

- Tab bar menus had to change to pills because of unsolvable issue with
the border-radius as tab bar renders a overlapping border onto the box
below. And I think pills look better.
- Added padding to code editor empty preview message
- Hide monaco's built-in blue focus border, we don't need it and it
never showed before either.
- Label add menu is simplified, removing the nested segment.
