Fix Bug #505: fallback修复
This commit is contained in:

|
||||
* 住院发退药业务中，发药明细（DispensingDetail）与发药汇总单（DispensingSummary）的
|
||||
* 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。
|
||||
*
|
||||
* 关键修复点（Bug #561）：
|
||||
* 医嘱录入后，总量单位（totalAmountUnit）显示为 “null”。根因是 OrderDetail 在保存时
|
||||
* 未从诊疗目录（CatalogItem）复制 totalAmountUnit 字段，导致前端读取到空值。
|
||||
* 现在在创建 OrderDetail 时，显式设置 totalAmountUnit 为对应 CatalogItem 的
|
||||
* totalAmountUnit（若目录中未配置则使用默认空字符串），并在查询时确保返回该字段。
|
||||
* 关键修复点（Bug #505）：
|
||||
* 当药品已由药房发药（DispenseStatus = DISPENSED）时，护士仍可在“医嘱校对”模块执行“退回”操作。
|
||||
* 该行为违背业务规则，导致药品状态不一致。现在在退回（return）相关业务入口统一加入
|
||||
* “只能在未发药或发药未完成状态下退回”的校验，若不满足抛出 BusinessException。
