fix(tests): satisfy mypy on the queue-item push tests

The #568 tests unpacked AsyncMock.await_args without narrowing its
Optional type and passed a SimpleNamespace where _format_task_detail
is annotated TaskTable. Narrow with the repo-standard 'assert
await_args is not None' and cast the fake task at the call sites.
