Add job tracking with PostgreSQL, image storage, and review workflow
- Add PostgreSQL service to docker-compose with health check and postgres_data volume
- Mount ./ocr_images as bind volume for persistent image storage
- Add backend/database.py with schema init and get_db() context manager
- Add 5 new API endpoints: POST /api/jobs, GET /api/jobs (search), GET /api/jobs/{id},
GET /api/jobs/{id}/image, PUT /api/jobs/{id}/review
- Jobs are saved with author/book/chapter/page metadata, auto UUID, and submitted_at timestamp
- Jobs start as 'unreviewed'; review captures edited text, reviewer name, and reviewed_at
- Add MetadataForm.jsx (author/book/chapter/page inputs) to the New Job panel
- Add JobsPanel.jsx with search/filter, paginated list, and detail pane with review form
- Add "Commit Job" button to ResultPanel (plain_ocr mode only) with success/error feedback
- Add "New Job" / "Browse Jobs" navigation to the app header
