  *   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。
  *
- *   根因分析：
- *   原逻辑在护士“执行”医嘱时直接插入状态为可见的明细记录，而汇总单仅在护士点击“汇总发药申请”时生成。
- *   在默认“需申请模式”下，药房会提前看到明细但看不到汇总单，导致配药与账务脱节。
- *
  *   解决方案：
- *   1. 引入系统参数 `nurse.submit.mode` 控制触发时机（默认 1=需申请模式，2=自动模式）。
- *   2. 需申请模式下：执行医嘱时明细状态置为 PENDING_APPLICATION（药房查询过滤不可见）。
- *   3. 汇总申请时：在同一事务内生成汇总单，并批量将关联明细状态更新为 APPLIED，实现状态强同步。
- *   4. 自动模式下：执行即同步生成明细与汇总，状态直接为 APPLIED。
+ *   1. 将发药明细写入与汇总单状态更新放在同一事务中，确保原子性。
+ *   2. 在发药完成后立即将对应的 ScheduleSlot 状态置为已取药（3），防止后续查询出现状态滞后。
+ *
+ *   此次提交同时修复 Bug #574：预约签到缴费成功后，数据库 adm_schedule_slot.status
+ *   状态未及时流转为 “3”（已取药）。在支付成功的业务路径中补充对 ScheduleSlot
+ *   的状态更新，并在异常情况下回滚，确保状态一致性。
