Fix Bug #561: fallback修复

* 3. OrderMain (挂号单) → CANCELLED（已取消）
|
||||
* 4. RefundLog → SUCCESS（退款成功）
|
||||
*
|
||||
* 关键修复点（Bug #505）：
|
||||
* 在“医嘱校对”模块，护士只能对状态为 {@link DispenseStatus#PENDING}（待发药）或 {@link DispenseStatus#REJECTED}（已退回）的医嘱执行“退回”操作。
|
||||
* 当医嘱已被药房发药（状态为 {@link DispenseStatus#DISPENSED}）时，抛出业务异常阻止退回。
|
||||
* 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 OrderDetail 在保存时未从
|
||||
* CatalogItem 中读取并写入对应的 totalUnit（总量单位）字段，导致前端取到 null。
|
||||
* 修复思路：
|
||||
* 1. 在创建 OrderDetail 时，确保从 CatalogItem 获取配置的单位（unit / totalUnit）。
|
||||
* 2. 对可能的空值做容错处理，防止 NPE。
|
||||
* 这样前端在展示医嘱列表时即可正确显示诊疗目录配置的单位。
