[BUG] - [3.2.2] 注册中心异常重启后，服务实例虽然重新注册了，但是实例在注册中心的状态会一直处于STARTING

### Steps to Reproduce

1. sdk版本为3.2.0
2. 当前版本的注册逻辑为在SCBEngine中在registrationManager.run执行完后，将注册中心的服务实例状态改为UP
3. 但是当注册中心异常重启后，服务重新注册时，并不会再修改注册中心服务实例的状态，从而导致注册中心中，服务实例的状态一直是STARTING

### Expected Behavior

注册中心异常后，服务实例重新注册能够将状态修改为UP

### Servicecomb Version
sdk版本为3.2.0

### Additional Context

_No response_

Start in SCBEngine around the registrationManager.run flow described in the issue, then trace what happens when a service registers again after the registry restarts. Confirm that re-registration also updates the registry instance state to UP rather than leaving it at STARTING. Reproduce the restart and re-registration sequence to verify the final state.
