refactor(grpc): drop storeResponseBody from GrpcMonitor request

gRPC checks always store the response body now — the backend removed the
per-check "store response body" toggle and no longer accepts or returns the
field. Remove it from the GrpcRequest construct type and the codegen emitter,
and drop it from the affected fixtures.
