  *   解决方案：

+ * 关键修复点（Bug #506）：
+ *   门诊诊前退号后，需要同步更新以下几张表的状态：
+ *     1. order_main / order_detail      -> OrderStatus.CANCELLED
+ *     2. schedule_slot                 -> ScheduleSlotStatus.AVAILABLE
+ *     3. schedule_pool                 -> SchedulePoolStatus.AVAILABLE
+ *     4. refund_log (若已退款)        -> RefundStatus.SUCCESS
+ *
+ *   之前的实现仅修改了 order_main，导致前端查询到的挂号状态与实际业务不符。
+ *   现在在同一事务内统一完成上述状态变更，确保数据一致性。
