[I] [Studio][Bug] Consumer Group APIs return generic 500 when providers are unavailable [rocketmq-dashboard]

Aias00 opened a new issue, #786:
URL: https://github.com/apache/rocketmq-dashboard/issues/786

   ### Before Creating the Bug Report
   
   - [x] I have confirmed this is not already covered by an existing issue or open pull request.
   
   ### Describe the Bug
   
   The Studio Consumer Group APIs are exposed by `ConsumerGroupController`, but the default provider/admin implementations behind those APIs still throw plain `UnsupportedOperationException` for Consumer Group operations.
   
   Because `UnsupportedOperationException` is handled by the generic exception handler, the API returns a generic HTTP 500 response instead of an explicit provider-unavailable response. Opening or operating the Consumer page in real API mode can therefore fail with an opaque internal error.
   
   Affected operations include:
   
   - List consumer groups
   - Get group progress
   - Get group subscriptions
   - Get consumer group detail
   - Create/delete consumer group
   - Reset consumer offset
   
   ### Steps to Reproduce
   
   1. Run Studio with the default provider/admin implementation.
   2. Call `/api/groups` or any Consumer Group detail/mutation endpoint.
   3. Observe that the provider/admin throws `UnsupportedOperationException` and the client receives a generic 500 response.
   
   ### What Did You Expect to See?
   
   Until real Consumer Group provider/admin support is wired, these APIs should return an explicit unavailable/unsupported business response, such as HTTP 501 with a clear message.
   
   ### What Did You See Instead?
   
   A generic internal server error is returned.
   
   ### Additional Context
   
   This is part of the Studio control-plane baseline hardening. Missing backend providers should be explicit capability gaps, not generic server failures.
