fix(Cadence): fixed legacy clusterMetadata default

It was broken since chart 0.18.0.

.Values.server.frontend.service.port is required
for the Cadence K8s service in the Helm chart,
thus it will always be defined, so I changed the
defaulting behavior to always use that, because it
would never fall back to the dockerize env var
.Env.FRONTEND_PORT or even back to literal 7933.
