Fix Bug #505: fallback修复

* 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。
|
||||
*
|
||||
* 解决方案：
|
||||
* 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。
|
||||
* 关键修复点（Bug #505）：
|
||||
* 当药品已由药房发药（DispenseStatus.DISPENSED），护士仍可在“医嘱校对”模块执行“退回”操作，
|
||||
* 这会导致已发药的订单被错误回退，破坏药品库存与业务流程。
|
||||
*
|
||||
* 解决方案：
|
||||
* 在执行退回（return）相关业务前，先校验医嘱主表的发药状态。
|
||||
* 若状态为 {@link DispenseStatus#DISPENSED}（已发药）或更高的已完成状态，则抛出业务异常，
|
||||
* 阻止后续的退回、撤销等操作。
|
||||
*
|
||||
* 该校验统一放在 {@link #validateReturnAllowed(OrderMain)} 方法中，并在所有
|
||||
* 可能触发退回的业务入口（如 {@link #returnOrder(Long)}、{@link #rejectOrder(Long)} 等）调用。
