Admin suite: monitoring dashboard, user management/ban, broadcast, reports, SMS test

- /Admin/Overview: platform monitoring stats (users by role, facilities, listings, applies, push subs, queue, reports, bans)
- /Admin/Users: search/filter + ban/unban (User.IsBanned + reason); banned users blocked at login
- /Admin/Broadcast: send announcement (in-app + web push) to all / staff / employers via NotificationService
- Reports: report button on shift/job detail → /report endpoint → /Admin/Reports (resolve/dismiss)
- Settings: 'send test SMS' button; admin cross-nav links; SMS API config already in place
- migration AdminBanReports; verified overview/users/broadcast/report persist
