  *   【住院发退药】发药明细（OrderDetail）与发药汇总单（OrderMain）数据的触发时机不一致，
  *   可能导致明细已写入而汇总单仍保持旧状态，业务出现脱节。根因是发药业务在同一事务
  *   中先插入明细后异步更新汇总单，异步任务未必及时完成。
- *
- *   解决方案：
- *   1. 将发药业务（dispenseDrug）改为同步执行，确保在同一事务内先更新汇总单状态，
- *      再插入明细，或反向顺序均可，但必须在事务提交前全部完成。
- *   2. 为防止以后出现类似异步更新，新增一个受保护的统一方法 `updateDispenseSummaryAndDetail`
- *      用于同时更新汇总单和明细，所有发药入口统一调用该方法。
- *   3. 在该方法内部先更新汇总单状态为 “已发药”(3)，随后批量插入明细记录，最后返回成功。
- *   4. 为兼容历史调用，保留原 `dispenseDrug` 方法签名，但内部直接委托到新实现。
- *
- *   这样可以保证“发药汇总单 → 发药明细” 数据在同一事务内一致提交，消除业务脱节风险。
