  *   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. 将发药明细与汇总单的状态写入统一放在同一事务中。
- *   2. 采用统一的状态枚举，避免硬编码。
- *
- * 关键修复点（Bug #506）：
- *   门诊诊前退号后，涉及 OrderMain、ScheduleSlot、SchedulePool、RefundLog 等表的状态
- *   必须统一使用业务常量，且必须与生产环境（PRD）定义保持一致。
- *   之前的实现仅修改了 OrderMain 状态，导致 ScheduleSlot/Pool 仍保持 “已预约” 状态，
- *   产生业务冲突（如号源无法被其他患者复用）。
- *
- *   解决方案：
- *   1. 在退号业务中统一更新以下表的状态：
- *      - OrderMain.status            -> OrderStatus.CANCELLED
- *      - ScheduleSlot.status         -> ScheduleSlotStatus.AVAILABLE
- *      - SchedulePool.status         -> SchedulePoolStatus.AVAILABLE
- *      - RefundLog.refundStatus      -> RefundStatus.SUCCESS（若已完成退款）
- *   2. 将上述更新放在同一事务内，确保原子性。
- *   3. 为防止遗漏，新增日志记录并在异常时回滚事务。
