Stop baking VITE_API_URL into the Vite build so one image can run against any backend. Container entrypoint (docker-entrypoint.d/30-frontend-config.sh, auto-run by the nginx image) writes /usr/share/nginx/html/config.js from the VITE_API_URL container env at every start; index.html loads it before the bundle, and agent.ts prefers window.__APP_CONFIG__ with the build-time env as fallback so local dev and vite preview behave exactly as before. public/config.js ships an empty placeholder for non-container builds. Changing backends is now a restart with new env, no rebuild.
