Various improvements for long file and commit names (#30374)

Fixes: https://github.com/go-gitea/gitea/issues/29438

This contains numerous enhancements for how large commit messages and
large filenames render. Another notable change is that the file path is
no longer cut off by backend at 30 chars, but rendered in full with
wrapping.

(cherry picked from commit 50099d7af436785daf66a3a9f27bd5c009f90684)

Conflicts:
	- templates/repo/diff/box.tmpl
          Picked Gitea's version, because it appears we missed a
          gt-gap-1 => tw-gap-1 conversion
	- web_src/css/repo.css
          Conflict due to tag signature highlighting, resolved by
          adding the Gitea changes on top of ours manually.
(cherry picked from commit 28170b517914f00449dbce8ba91e02fa1f0f84e5)
