feat: admin dashboard with user management and delete capabilities

- Add tabbed admin UI (Spaces | Users) with auth gate
- Add admin API endpoints on EncryptID: list users, delete user, clean space members
- Add admin force-delete space endpoint on rSpace (bypasses owner check)
- Protect all admin endpoints with ADMIN_DIDS env var
- Add ADMIN_DIDS to both Docker Compose configs
