fix: register infinite loading behind reverse proxy

- Add app.set('trust proxy', 1) in Express to fix ERR_ERL_UNEXPECTED_X_FORWARDED_FOR
  error thrown by express-rate-limit when deployed behind Nginx

- Add ARG/ENV VITE_API_URL and VITE_WS_URL in client/Dockerfile so Docker
  build args from docker-compose.yml are properly injected into the Vite bundle
  (previously fell back to hardcoded http://localhost:3001)
