[I] [Studio][Bug] Instance-scoped cluster detail can return a cluster outside the configured instance scope [rocketmq-dashboard]

X-LightYear opened a new issue, #4994:
URL: https://github.com/apache/rocketmq-dashboard/issues/4994

   ### Before Creating the Bug Report
   
   - [x] I searched open and closed issues and pull requests for `refreshClusterDetail`, instance-scoped cluster detail, configured cluster scope, and cross-instance cluster resolution.
   - [x] I reproduced the behavior on the current `rocketmq-studio` baseline (`1ef5d8607`).
   - [x] A deterministic regression test fails against the current production code.
   
   ### Problem
   
   The instance-scoped cluster detail endpoint can return a physical cluster that is not within the selected instance's configured cluster scope.
   
   When an Apache Studio instance is configured with a specific cluster name but its NameServer exposes multiple clusters, `GET /api/clusters/{id}?instanceId=...` does not apply the same configured-cluster filter used by `GET /api/clusters?instanceId=...`.
   
   ### Steps to Reproduce
   
   1. Configure an Apache instance `instance-a` whose endpoint exposes `ConfiguredCluster` and `OtherCluster`.
   2. Configure the instance's selected/default cluster as `ConfiguredCluster`.
   3. Call `GET /api/clusters/OtherCluster?instanceId=instance-a`.
   4. Observe the returned cluster detail.
   
   ### Expected behavior
   
   An instance-scoped detail request must reject or return no result for a cluster outside that instance's configured scope, consistently with the instance-scoped cluster list.
   
   ### Actual behavior
   
   The endpoint returns a populated `ClusterVO` for `OtherCluster`.
   
   ### Root cause
   
   `RocketMQClusterProvider.discoverClusters(String instanceId)` filters the discovered list with `configuredClusterName(instanceId)`, but `refreshClusterDetail(String clusterId, String instanceId)` looks up `clusterId` directly in the NameServer cluster table without applying that scope.
   
   ### Regression evidence
   
   `RocketMQClusterProviderTest.refreshClusterDetailShouldRejectClusterOutsideConfiguredInstanceScope` fails on the current baseline with:
   
   ```text
   expected: null
   but was: ClusterVO(id=OtherCluster, ...)
   ```
   
   ### Scope
   
   This is limited to the instance-scoped cluster detail read path. The requested fix should preserve global cluster detail behavior when no `instanceId` is supplied.
   
   ### Are you Willing to Submit a Pull Request?
   
   Yes.
