* 门诊预约挂号成功后,未实时累加 {@link SchedulePool#bookedNum},导致
* 可预约人数统计不准确。新增对 {@code SchedulePool} 的乐观锁更新,
* 确保在同一时间段的并发预约能够正确累计。
* 关键修复点Bug #506
* 门诊诊前退号后,涉及 OrderMain、OrderDetail、ScheduleSlot、SchedulePool、RefundLog
* 等多表的状态更新未严格遵循产品需求PRD。原实现使用了错误的状态枚举导致
* 数据库中状态值与前端展示、统计口径不一致。此处统一使用 PRD 定义的状态:
* • OrderMain -> OrderStatus.CANCELLED
* • OrderDetail -> OrderStatus.CANCELLED
* • ScheduleSlot-> ScheduleSlotStatus.AVAILABLE
* • SchedulePool-> SchedulePoolStatus.AVAILABLE
* • RefundLog -> RefundStatus.SUCCESS
*
* 同时保证在同一事务内完成所有表的更新,防止部分成功、部分失败导致数据不一致。
