feat: add Docker-based RustDesk Server (hbbs/hbbr) for VPS

- Add docker-compose.vps.yml with hbbs + hbbr services
- Update rustdesk-dummy.service with corrected binary path (/usr/share/...)
- Update xorg-dummy.service without -nolisten local (fixes socket access)
- Update install.sh for dummy driver + EDID fallback approach
- Update README with dual setup (host + VPS) and server instructions
- VPS: RustDesk Server runs via Docker on ports 21115-21119
