      * 医嘱退回操作
      * Bug #505 Fix: 增加发药状态前置校验，阻断已发药医嘱的直接退回
+     *
+     * 业务说明：
+     * 1. 退回前必须检查「发药明细」的状态以及「发药汇总单」的状态。
+     *    - 明细状态 (pharmacy_apply_status) 为 0 表示未发药，可退回；
+     *    - 汇总单状态 (summary_status) 为 0 表示未完成发药，也可退回。
+     *    任意一个已进入发药流程（>0）都不允许直接退回，以防止业务脱节。
+     * 2. 通过一次事务同时更新明细状态和汇总单状态，确保两者保持一致。
