Fix Docker container Python dependencies issue

Dockerfile Fixes:
- Copy Python packages to /home/appuser/.local instead of /root/.local
- Create appuser home directory before copying packages
- Update PATH to use /home/appuser/.local/bin
- Set proper ownership of .local directory for appuser
- Ensure appuser has access to installed Python packages

 Problem Solved:
- Container was failing with 'ModuleNotFoundError: No module named requests'
- appuser couldn't access packages installed in /root/.local
- Python dependencies now properly accessible to non-root user

 Docker container should now start successfully with all dependencies
