/**
|

* 医嘱退回（退号）业务。
|
||||
* 诊前退号（取消）业务。该方法在同一个事务内完成以下操作：
|
||||
* <ul>
|
||||
* <li>将 order_main.status 更新为 {@link OrderStatus#CANCELLED}</li>
|
||||
* <li>将所有关联的 order_detail.status 同步为 {@link OrderStatus#CANCELLED}</li>
|
||||
* <li>释放占用的号源：schedule_slot.status 设为 {@link ScheduleSlotStatus#AVAILABLE}</li>
|
||||
* <li>对应的 schedule_pool.used_count 减 1（若大于 0）</li>
|
||||
* <li>记录退款日志（refund_log）</li>
|
||||
* </ul>
|
||||
*
|
||||
* <p>Bug #505 修复要点：
|
||||
* 当药品已由药房发药（DispenseStatus.DISPENSED）时，护士不应再能够在“医嘱校对”模块执行退回操作。
|
||||
* 因此在退回前需要检查对应的 {@link DispensingDetail} 状态，若已发药则抛出 {@link BusinessException}。</p>
|
||||
*
|
||||
* @param orderMainId 主医嘱 ID
|
||||
* @param reason 退回原因
|
||||
* @param orderId 需要退号的医嘱主键
|

* @param refundReason 退款原因，可为空
