fix: replace broad Exception and print() with proper error handling in faces.py

`db_update_face_cluster_ids_batch` in `faces.py` has two problems:

- Uses broad `except Exception` instead of `sqlite3.Error`
- Uses `print("Error updating face cluster IDs in batch.")` instead of proper logging

### Proposed fix
- Replace `except Exception` with `except sqlite3.Error`
- Replace `print()` with `logger.error()`
- Add `import logging` and `logger = logging.getLogger(__name__)`

I'd like to fix this if maintainers agree.
