fix: complete integration test mock infrastructure for dominodatalab

- Add mock endpoint for version-specific PyPI API (/pypi/dominodatalab/2.0.0/json)
- Include 'urls' field in main PyPI endpoint for grayskull sdist discovery
- Add spdx.org/* to transparent URLs (grayskull license discovery)
- Store full PyPI metadata response for reproducible testing
