feat(archive): implement comment.archived and add archive page (#1074)

* feat(archive): implement comment.archived and add archive page

Add isCommentArchived() utility, /board/:boardIdentifier/archive route,
archive view with filtered feed, and UI integration (board buttons, edit
menu, catalog row, post). Archived indicator on catalog and posts.

* fix(archive): address review feedback from Bugbot and CodeRabbit

Add missing i18n keys (archived, thread_archived, view, loading_archive),
add /archive/settings route, replace hardcoded English in archive.tsx, and
fix mobile test state.
