refactor: update gRPC client initialization in model service tests

- Replaced direct gRPC client instantiation with a call to GetGrpcClient().Start() for improved consistency and maintainability across test cases.
- Cleaned up unnecessary imports in model_service.go to streamline the codebase.
- Enhanced test setup by ensuring the gRPC client is properly initialized before executing service methods.
