Fix artifact path resolution for workspace upload

- Update upload-artifact paths to use `${{ env.HOME }}` ensuring that `$HOME/tooling` and `$HOME/test_dependencies` are correctly resolved.
- Ensure consistency between artifact upload and download paths for reliable workspace restoration.
- Retain prior improvements for authentication, caching, and overall workspace management.

This change fixes the artifact upload failure due to literal `$HOME` usage.
