Fix pip-audit constraints for Py3.8/3.14 & cleanup

- Split pip-audit dependency logic:
  - Unpin pip-audit for Python < 3.9 to allow downgrading. This resolves the packaging version conflict on Ubuntu 20.04.
  - Enforce pip-audit >= 2.6.0 for Python >= 3.14, as safety dependencies are currently broken on 3.14.
- Remove obsolete arm64-support.json.
- Cleanup dependency comments.
