[July 31, 2025] Optimization of the futures order placement interface logic

Interface: /api/v2/mix/order/place-order

Changes:

before: In hedge mode, if the existing quantity is equal to the limit close order of the position, a newly added market close order will report an error due to insufficient position and will not automatically cancel the limit order that has occupied the position.
after: In hedge mode, if the existing quantity is equal to the limit close order of the position, a newly added market close order will automatically cancel the limit order that has occupied the position (consistent with Web/APP).
