Fix Bug #505: fallback修复

* 并将 schedule_pool.used_count -1（若大于0）以恢复号源库存。
|
||||
* 5. 记录退款日志（refund_log），确保审计完整。
|
||||
*
|
||||
* 关键修复点（Bug #561）：
|
||||
* 医嘱录入后，总量单位（totalUnit）显示为 “null”。根因是创建 OrderDetail 时未从诊疗目录
|
||||
* （CatalogItem）中读取并写入单位字段，导致前端渲染时取到空值。
|
||||
*
|
||||
* 解决方案：
|
||||
* 1. 在保存医嘱明细（OrderDetail）时，显式把诊疗目录的计量单位（catalogItem.unit）复制到
|
||||
* OrderDetail.totalUnit 字段。
|
||||
* 2. 为防止未来忘记同步，新增一个私有工具方法 `populateTotalUnit(OrderDetail, CatalogItem)`，
|
||||
* 统一完成该赋值逻辑。
|
||||
* 3. 在批量保存明细的入口统一调用该方法，确保所有新建的明细都有正确的单位。
|
||||
* 关键修复点（Bug #505）：
|
||||
* 医嘱已由药房发药（dispense_status = {@link DispenseStatus#DISPENSED}），护士仍能在
|
||||
* “医嘱校对”模块执行“退回”操作。此行为违背业务规则，退回只能在药房未发药前进行。
|
||||
* 为此在退回（return）业务入口统一加入状态校验，若存在已发药的明细则抛出
|
||||
* {@link BusinessException}，并在前端展示相应错误提示。
