feat: poll Teams presence independently of AIDA CSV

- Teams status is now always queried, even without AIDA CSV
- Users without personal_nr are also polled (Teams-only mode)
- If AIDA is unavailable, default to 'anwesend' and use Teams color
- Dashboard will now show Teams status even without SMB mount
