Prevent tab shifting, remove extra margin on fluid pages (#31090) (#31099)

Backport #31090 by @silverwind

1. Extend concept of https://github.com/go-gitea/gitea/pull/29831 to all
tabular menus, there were only three left that weren't already
`<overflow-menu>`.

2. Remove extra padding on `fluid padded` container like for example PR
diff view. The page margin is already correctly sized via
`.ui.container`, so this was just extraneous padding that looked ugly.

3. Replace `gt-word-break` with `tw-break-anywhere` in issue-title,
fixing overflow.
