fix: match original Dockerfile + pin huggingface_hub==0.19.4 in requirements.txt

- Revert Dockerfile to original (bare pip installs, matching zenotaiz original)
- Only pin huggingface_hub==0.19.4 in requirements.txt for cached_download compat
- HF Spaces Docker SDK processes requirements.txt after Dockerfile build
