fix: resolve 8 test failures from missing requests stub and wrong python path

- Add `requests` to conftest.py module stubs so patch("requests.post") works
  in reward scoring tests without the package installed
- Use sys.executable instead of bare "python" in git safety tests so the
  subprocess finds pytest from the venv rather than system python
