modify ServiceType LoadBalancer -> NodePort, service Port's nodePort as the host cluster may have already allocated this port number

[Lanyujiex]

There is a certain probability of service nodeport duplication, as the host cluster may have already allocated this port number. This can lead to successful modifications within the vcluster, but the changes cannot be synchronized to the host cluster.

my error logs:

2025-09-04 14:44:03     ERROR   controller/controller.go:341    Reconciler error        {"component": "vcluster", "controller": "service", "namespace": "default", "name": "deepseek-svc", "reconcileID": "a4b4b229-3bd4-4784-9ba3-650c71f734b5", "error": "sync: patch host object: update object: Service \"deepseek-svc-x-default-x-tenant-61616664-textxl\" is invalid: spec.ports[0].nodePort: Invalid value: 30080: provided port is already allocated"}

Do we have any good solutions to this problem？
