Describe the bug

StatefulSet created by RBG has a serviceName: <rbg_name>-<role>

apiVersion: apps/v1
kind: StatefulSet
spec:
  serviceName: sglang-pd-qwen3-decode

However, the related service created by RBG has a different name:

$ kubectl get svc
s-sglang-pd-qwen3-decode           ClusterIP   None            <none>        <none>     2m20s

The inconsistency may cause some service discovery issues.

Reproduction

Any RBG using statefulset will be affected.

Environment

RBG version: abe8e15
Kubernetes version: 1.34
