 /**
  * 病历业务实现
- * 
- * 修复 Bug #562：待写病历列表加载缓慢且前端一直转圈。
- * 根因：原查询未使用分页，导致全表扫描+多表关联，数据量大时响应>2s；
- *       前端未处理异常/超时分支，loading 状态未重置。
+ *
+ * 修复 Bug #562：待写病历列表加载超时/假死
+ * 根因：原实现未启用分页且直接查询完整病历实体（含大文本字段 emr_content），
+ * 导致全表扫描、内存溢出风险及序列化耗时过长。
+ * 修复方案：
+ *   1. 强制分页查询，限制单次返回数据量
+ *   2. 使用 DTO 投影，仅返回列表展示所需字段
+ *   3. 标记 @Transactional(readOnly = true) 优化数据库连接池与事务开销
