  * 新增修复（Bug #506）：
  *   门诊诊前退号后，需要同步更新以下几张表的状态，使其与 PRD 定义保持一致：

- * 新增修复（Bug #503）：
- *   住院发退药时，发药明细（DispensingDetail）与发药汇总单（DispensingSummary）在
- *   数据库写入的时机不一致，导致汇总单可能未及时反映最新的明细，产生业务脱节风险。
- *   解决方案：
- *     1. 将发药明细的写入与汇总单的更新放在同一个事务中完成。
- *     2. 在明细写入后立即调用 {@link #updateDispensingSummary(Long)}，根据
- *        明细的药品、数量等重新计算并写入汇总单。
- *     3. 为防止并发导致的脏读，使用 `@Transactional(propagation = REQUIRED)` 保证原子性。
- *
- *   以上改动确保每一次发药或退药操作，汇总单始终保持与明细数据一致，消除业务脱节风险。
