* 住院发退药业务中发药明细DispensingDetail与发药汇总单DispensingSummary
* 数据写入时机不一致,导致两者状态不匹配,存在业务脱节风险。
*
* 解决方案
* 1. 将发药业务统一放在同一个 @Transactional 方法中,确保两张表的写入要么全部成功要么全部回滚
* 2. 先生成并持久化 DispensingSummary再生成对应的 DispensingDetail。
* 3. 在写入明细前,将明细的状态显式设置为与汇总单相同的状态(如 DISPENSED避免因默认值导致的不一致。
* 4. 完成后统一更新 OrderMain 的发药状态,确保业务层面的状态同步。
* 新增修复Bug #575
* 预约成功后,实时累加 SchedulePool.booked_num防止出现已预约数未更新的情况

* 为了修复 Bug #503整个过程必须在同一个事务完成:
* 1. 创建并持久化 DispensingSummary汇总单
* 2. 根据汇总单创建对应的 DispensingDetail明细并显式设置状态;
* 3. 更新 OrderMain、OrderDetail 等相关表的状态
* 4. 如有异常,事务回滚,保证两张表的数据一致性
* 该方法在事务完成:
* 1. 插入 OrderMain、OrderDetail 等基础数据
* 2. 更新对应的 ScheduleSlot 状态;
* 3. **实时累加 SchedulePool.booked_num**Bug #575 修复点)
* 4. 其它业务如费用计算、队列排号等
*
* @param orderMainId 主医嘱 ID
* @param dispenseItems 需要发药的药品明细药品ID、数量等
* @param orderMain 订单主表信息,必须包含 schedulePoolId、scheduleSlotId 等字段
* @return 创建成功的订单主键 ID
