Replace NGINX with Vite dev server in Docker setup (#777)

- Use Node.js runtime instead of OpenResty/NGINX
- Clone isle.pizza frontend from master branch
- Add entrypoint script that runs prepare:assets and starts Vite
- Remove ISLE_EMSCRIPTEN_HOST build flag
- Delete nginx.conf (no longer needed)
