fix(docker): resolve 'No module named reflex' in pod

Problem: Python packages installed in /root/.local but container runs as
non-root user 'peikarband' who cannot access /root/ directory.

Solution:
- Create user before copying dependencies
- Copy packages to /home/peikarband/.local instead of /root/.local
- Update PATH to point to user's local bin directory
- Fix ownership of copied files

This ensures the non-root user can access all Python packages including reflex.
