Show only author and co-authors without committer, and deduplicate the
same user with multiple email addresses.
The commit list "Author" column should not show the committer. This is
somewhat misleading, and arguably showing it on the individual commit
page is sufficient and consistent with other forges.
The same user with multiple email addresses often happens when
DEFAULT_KEEP_EMAIL_PRIVATE is enabled and Gitea does not use an actual
email address by default for edits. Showing the same avatar and name
twice is not helpful then.

Parse `Co-authored-by:` trailers from commit messages and surface
contributors as an avatar stack across the commit page, commits list, PR
commits tab, latest-commit row, blame, graph, and dashboard feed.
- Up to 10 visible 20px avatars, GitHub-style overlap (6px first stride,
4px between subsequent), `+N` chip for the rest.
- Label: 1 → name; 2 → `<a> and <b>`; 3+ → `<N> people` opens a Tippy
popup with all participants.
- Names and avatars link to the repo's commits-by-author search; fall
back to profile or `mailto:`.
- Trailer parsing uses `net/mail.ParseAddress`, scans only the trailing
paragraph, filters out the commit's own author/committer.
- Drops the non-standard `Co-committed-by:` emission on squash merge and
web edits.
Devtest: `/devtest/coauthor-avatars`.
