feat: unanswered ticket badges, dashboard counts, cross-department ticket creation

- Add /tickets/unanswered-counts API endpoint for staff/admin
- Show red badge with unanswered count on sidebar nav (staff tickets, admin tickets)
- Add summary cards (unanswered/answered/total) to staff tickets page
- Highlight unanswered count in admin tickets stats cards
- Staff can create tickets to OTHER departments only (not their own)
- Frontend hides own department from ticket creation dropdown
- Sidebar badges auto-refresh every 30 seconds
