allocateRoutePorts() was using the route's port field (the mc-proxy
listener port, e.g. 443) as the container internal port in the podman
port mapping. For L7 routes, apps don't listen on the mc-proxy port —
they read $PORT (set to the assigned host port) and listen on that.
The mapping host:53204 → container:443 fails because nothing listens
on 443 inside the container. Fix: use hostPort as both the host and
container port, so $PORT = host port = container port.
Broke mcdoc in production (manually fixed, now permanently fixed).
