Add Docker deployment and Apache reverse proxy setup

🐳 Docker Implementation:
- Add Dockerfile with Alpine Linux (46MB image)
- Add docker-compose.yml with production-ready config
- Add manage-relay.sh for easy local management
- Add stella-relay.service for systemd auto-start
- Published images: silberengel/orly-relay:latest, :v1, :v2

🔧 Apache Reverse Proxy:
- Add comprehensive Apache proxy guide for Plesk and standard Apache
- Add working WebSocket proxy configuration (ws:// not http://)
- Add troubleshooting guide based on real deployment experience
- Add debug-websocket.sh script for systematic diagnosis
