Add Docker deployment for Unraid

- Dockerfile with nginx:alpine for static file serving
- docker-compose.yml with port 9113:80 mapping
- deploy.sh for git-based deployment to Unraid
- setup-unraid.sh for initial server configuration
- manage.sh for container operations (logs, status, restart, etc.)
- .gitignore to exclude config.js
