Implement rootless Docker container with enhanced security and preserved TFTP logging (#87)
* Implement rootless Docker container with preserved TFTP logging

- Convert all processes to run as non-root user (nbxyz) for enhanced security
- Add customizable PUID/PGID environment variables for volume permission management
- Implement privilege dropping using gosu for secure initialization
- Optimize Dockerfile with multi-stage build and better caching
- Create dnsmasq wrapper script to ensure TFTP logs appear in docker logs
- Configure supervisord to properly forward dnsmasq output to container stdout
- Maintain full TFTP/PXE boot debugging functionality for users

Security improvements:
- All application processes (nginx, webapp, dnsmasq) run as nbxyz user
- Only supervisord initialization runs as root, then drops privileges
- Proper permission management for all service directories
- Configurable user/group IDs via PUID/PGID environment variables

Performance optimizations:
- Multi-stage Docker build reduces final image size
- Better layer caching for faster rebuilds
- Optimized package installation and cleanup
