Ben 2ec7b7ca09 fix: disable conflicting legacy authentication system for master trainer pages
- Commented out check_master_dashboard_auth hook to prevent conflicts
- The centralized HVAC_Access_Control system now handles all master trainer authentication
- This resolves the dual authentication system conflict causing persistent redirects
- Master trainer pages should now load properly without authentication loops
