fix(deploy): forward MODULES_ENTITLED into the server container (default parking,validation)

The Komodo stack env alone is compose interpolation input; only variables in the
service's environment: block reach the container. Without it every booth on 55d6242
had Car Wash entitled (unset = every module).
