Fix production deployment for public site routing

- pass `NEXT_PUBLIC_CARPLACE_URL` into the production Docker build
- keep `NEXT_PUBLIC_STOREFRONT_URL` as a backward-compatible fallback
- run the production deploy script from the Gitea workflow after building
- include `homepage` in production deploy, pull, and health-check service lists
- allow deploy to use a release image already built locally on the VPS
