fix: refresh token re-reads role from DB; remove staff stats cards

- /api/auth/refresh now fetches current role from DB instead of using
  stale Redis payload — role changes now take effect on next page refresh
  without requiring re-login. Also deactivates token if user.active=false.
- Removed role-count stat cards from staff page (user request)
