- Add test for stoploss_query_requires_stop_flag in _ft_has. - Replace _fix_trigger_order_id tests with base class integration tests (verify stop=True is passed by fetch_stoploss_order/cancel_stoploss_order). - Add tests for stop param flow: passed to history endpoints, stripped from open orders query. - Remove obsolete cancel_stoploss_order/fetch_stoploss_order override tests.
