Fix Dockerfile: Add proper user setup for HF Spaces

- Create user with UID 1000 (required by HF Spaces)
- Set HOME and PATH environment variables
- Switch to non-root user before pip install
- Fix permission issues with git config commands
- Use --chown for proper file ownership

This fixes the "could not lock config file" error.
