fix: resolve JSON serialization in list_bids and add orders endpoint

- Convert SQLAlchemy objects to dictionaries in list_bids method
- Add GET /v1/marketplace/orders endpoint for CLI compatibility
- Fixes 500 error when listing bids
- Fixes 404 error when CLI calls orders endpoint
- Orders endpoint returns bids in expected format
