Serve with Node/Express instead of nginx (matches working astroreal pattern)

- Add server.js: Express serves dist/ + injects env (GA_ID, FORM_EMAIL, GMAP) at runtime
- Container port now 4321 (identical to moreminimore-astroreal that deploys on EasyPanel)
- Remove nginx.conf + entrypoint.sh (no longer needed); Dockerfile uses node server.js
- Verified: pnpm build + node server.js -> all 40 pages serve 200, env injected, 0 leftovers
