Fix: dashboard domain filters only apply to local cluster

Remote clusters without explicit domain filters now get no filtering
instead of inheriting dashboard-level filters. This matches the behavior
of other selectors (gateway/ingress/httproute) which already only apply
dashboard-level config to the local cluster.
