  *   4. 为兼容历史数据，若 CatalogItem 中的 totalUnit 为空，仍使用旧字段 unit 作为回退。

  *   以上改动集中在 `saveOrderDetail` 方法中，确保每一次医嘱明细写入都携带正确的计量单位。

+ * 新增修复（Bug #562）：
+ *   门诊医生工作站‑待写病历列表加载慢（>2 秒），根因是一次性查询所有待写
+ *   病历时未使用分页，导致大量数据一次性返回并在前端渲染时卡顿。
+ *
+ *   解决方案：
+ *   1. 为 `listPendingRecords`（即待写病历查询）统一加入分页控制，默认返回 20 条。
+ *   2. 前端若未传入 pageSize，则使用默认值；若传入则以传入值为准。
+ *   3. 同时对查询条件做必要的索引过滤，避免全表扫描。
+ *   4. 返回的 Page 对象包含 total、pages 等信息，前端可据此实现分页。
