Fix code review issues in commissioner management

- Add success/error feedback banners to commissioner add/remove actions
- Gate allUsers query to admin-only (prevents exposing all users to non-admin commissioners)
- Prevent commissioner self-removal in both action (server) and UI (client)
- Add "(you)" label next to current user in commissioner list
- Remove all unnecessary `any` type casts in favor of inferred types
