Fix integration test to use new proto message names

Updated TestControllerGrpcEndpoints.testGetClusterHealthStoresGrpcEndpoint
to use the new proto message types:
- GetClusterHealthStoresGrpcRequest → GetStoreStatusRequest
- GetClusterHealthStoresGrpcResponse → GetStoreStatusResponse
- Changed from map access to repeated StoreStatus list

This aligns with the proto changes made in commit 12aaa8f which
refactored the proto messages per PR review feedback.

Test now passes:
✅ testGetClusterHealthStoresGrpcEndpoint PASSED (227 ms)
