Update test to verify mask generation and add psutil dependency

Test improvements:
- Call Gradio API directly to receive all 3 outputs (text, viz, mask)
- Verify mask is returned (not None)
- Verify mask shape and dtype are correct
- Upload both RGB + depth images to API
- Check for successful estimation in output text

Bug fix:
- Add psutil==6.1.1 to Dockerfile.base dependencies
- Resolves: "No module named 'psutil'" import error
- Required by FoundationPose modules
