突然想到，我好像可以只用一个 maa、两个配置、一个模拟器，定时切换配置运行就行。

Hi @aryan-curiel, just wanted to say a huge thank you for this PR! The OrderingSchema implementation is incredibly clean, elegant. It's exactly the solution I was looking for. Amazing work!

I noticed that when order_by is empty ([]), calling `queryset.order_by()` clears the model's default ordering from Meta.ordering. Maybe we should only call `order_by()` when there are actual fields to sort...
