feat: Add nginx configuration for static frontend serving

- Update docker-compose.yml to use nginx for static file serving
- Configure nginx to serve frontend static files and proxy API requests
- Add frontend-init container to copy static files to nginx volume
- Update nginx/default.conf with proper static file handling and gzip compression
- Add NGINX_SETUP.md documentation for nginx deployment
- Improve performance by separating static files from backend API

Changes:
- Frontend static files now served by nginx (better performance)
- Backend only handles API requests (port 8000, internal)
- Gzip compression and caching for static assets
- WebSocket support for console functionality
- Health check endpoint for monitoring
