Fix Bug #506: fallback修复

*
|
||||
* 修复 Bug #505、#503、#506、#561 等。
|
||||
*
|
||||
* 关键修复点（Bug #503）：
|
||||
* 住院发退药场景中，发药明细（DispensingDetail）与发药汇总单（OrderMain.dispenseStatus）在业务触发时机不一致，
|
||||
* 可能出现“明细已生成”而汇总单仍保持未发药状态，导致后续退药、统计等流程出现业务脱节风险。
|
||||
* 关键修复点（Bug #506）：
|
||||
* 门诊诊前退号后，涉及的多张表（order_main、order_detail、schedule_slot、schedule_pool 等）状态未统一
|
||||
* 与生产环境（PRD）定义不符，导致前端显示状态错误、后续排班冲突等问题。
|
||||
*
|
||||
* 解决思路：
|
||||
* 1. 将发药操作全部放在同一个 @Transactional 方法中，确保原子性。
|
||||
* 2. 先持久化发药明细（包括批次、数量等），随后立即更新对应医嘱主表的发药状态为 {@link DispenseStatus#DISPENSED}。
|
||||
* 3. 若明细插入失败或状态更新失败，统一回滚事务，避免出现“明细已生成、汇总未更新”的不一致状态。
|
||||
* 1. 将退号（退款）业务全部放在同一个 @Transactional 方法中，确保原子性。
|
||||
* 2. 统一使用 {@link OrderStatus#CANCELLED} 作为退号后医嘱主表的状态。
|
||||
* 3. 对应明细表（order_detail）状态同步更新为 {@link OrderStatus#CANCELLED}。
|
||||
* 4. 释放已占用的号源：将 schedule_slot.status 设为 {@link ScheduleSlotStatus#AVAILABLE}，
|
||||
* 并将 schedule_pool.used_count -1（若大于0）以恢复号源库存。
|
||||
* 5. 记录退款日志（refund_log），确保审计完整。
|
||||
* 6. 若任意一步失败，统一回滚事务，避免出现“部分表已更新、部分表未更新”的不一致状态。
|
||||
*
|
||||
* 为此在 {@link #dispenseOrder(Long, List<Long>)} 方法中重新组织代码顺序，并在异常捕获后抛出统一的 BusinessException。
|
||||
* 为此在 {@link #cancelOrderPre(Long orderId)} 方法中重新组织代码顺序，并在异常捕获后抛出统一的 BusinessException。
|
||||
*
|
||||
* 同时保留原有的业务日志记录，以便审计。
|
||||
*
|
||||
* 关键修复点（Bug #505）：
|
||||
* 在“医嘱校对”模块，护士可以对已由药房发药的医嘱执行“退回”操作，导致业务不一致。
|
||||
* 解决方案：在退回（return）业务入口处增加对 {@link OrderMain#dispenseStatus} 的校验，
|
||||
* 当状态为 {@link DispenseStatus#DISPENSED}（已发药）时抛出业务异常，阻止退回。
