Fix some UI alignments (#25277) (#25290)

Backport #25277 by @wxiaoguang

Fixes: https://github.com/go-gitea/gitea/issues/25282

Fix the problems:

1. The `repo-button-row` had various patches before, this PR makes it
consistent
2. The "Add File" has wrong CSS class "icon", remove it
3. The "Add File" padding was overridden by "!important", fix it by
`.repo-button-row .button.dropdown` with comment
4. The selector `.ui.segments ~ .ui.top.attached.header` is incorrect,
it should use `+`

The `repo-button-row` is only used on 3 pages:
