+/**
+ * 门诊医嘱相关数据库操作 Mapper
+ *
+ * 关键修复（Bug #561）：
+ * 1. 在查询医嘱列表时，联表查询字典表（his_dict）获取“总量单位”的中文名称。
+ *    之前仅返回 total_unit_id，导致前端展示为 null 或者数字 ID。
+ *    现在返回 total_unit_name，并映射到 DTO 的 totalUnitName 字段。
+ *
+ * 关键修复（Bug #562）：
+ * 2. 为防止一次性查询全部医嘱导致页面加载卡顿，新增默认分页限制（前端可自行扩展）。
+ *    当前查询仅返回前 200 条记录，足以满足“待写病历”列表的快速展示需求。
+ *    如需完整数据，可在业务层自行实现分页参数。
