Announcements: a Super Admin (or an Admin individually flagged via profiles.can_post_announcements) can post/retire a site-wide banner. Account migration: a Super Admin can move a locked-out user's diagrams, private catalog entries, and submissions to another account, with a migration-history log; ProfileModal adds the self-service half (link a new Google identity via Supabase manual linking, then unlink the old one, while signed in as the account being migrated). Also reworks the top bar's flat button row into grouped dropdown menus (Diagram / Admin / Account) now that there are enough entries to need it.
