🐛 Error Fixed:
- NameError: name 'BackupJob' is not defined in backup_cancel view
- Added missing 'from stiftung.models import BackupJob' import
✅ Backup cancellation now works correctly
- Users can cancel long-running backup jobs without errors
- Added local import following the same pattern as other backup functions
The error occurred when trying to cancel a running backup job due to missing model import.
