Auth:
- Add middleware.ts that redirects unauthenticated users to Authentik SSO
- Extract authOptions to shared auth-options.ts
- Add getAuthSession() helper for API route protection
- Add loading spinner during session validation
- Dev mode bypasses auth (stub user still works)
ManicTime:
- Fix hardcoded companyId="beletage" — now uses group context from Tags.txt
- Fix extended project format label parsing (extracts name after year)
