* 住院发退药业务中，发药明细（DispensingDetail）与发药汇总单（DispensingSummary）的

* 关键修复点（Bug #561）：
|

* 医嘱录入后，总量单位显示异常，显示为“null”。根因是保存 OrderDetail 时未从
|

* CatalogItem（诊疗目录）读取配置的计量单位。现在在保存医嘱时补全
|

* totalAmountUnit，并在查询时对历史遗留的 null 进行兜底填充。

* 新增修复（Bug #575）：

* 预约成功后，adm_schedule_pool 表的 booked_num 未实时累加，导致号源余量显示不准确。
|
||||
* 在创建订单并确认支付成功后，显式更新 SchedulePool.bookedNum 并使用乐观锁防止并发超卖。
