feat(25-02): add doctor and repair Quick Action buttons

- Add 'paperforge-doctor' action: runs 'python -m paperforge doctor'
- Add 'paperforge-repair' action: runs 'python -m paperforge repair'
- ACTIONS array now has 4 entries: sync, ocr, doctor, repair
- Existing _runAction() handles both new commands unchanged (thin CLI shell)
