Add web frontend and Docker deployment
Introduce a new web frontend and containerized deployment setup. Adds a Vite/React+TypeScript web scaffold (package.json, src/, index.html, tailwind/postcss configs, tsconfig, and package-lock) plus an Nginx config for proxying /api to the Go gateway and SPA fallback. Add Dockerfiles for the Go gateway and the web app, and a docker-compose.yml that defines gateway and web services (ports, healthcheck, volume for gateway data, and gateway dependency for web). Update .gitignore to exclude frontend node_modules and build outputs.
