Add unit tests to CI workflow and clean up dependencies

- Add unit-tests job to build-and-test.yaml for Python 3.8
- Keep existing vulnerability-scan job using shared action
- Add dev dependencies (pytest, pytest-cov, unittest-xml-reporting) to pyproject.toml
- Remove setuptools from runtime dependencies (only needed for build)
- Tested locally: 287 tests pass successfully
