/**
* 门诊病历业务实现
*
* 修复 Bug #562：待写病历数据加载超过2秒且一直转圈。
* 根因分析：
* 1. 原查询未使用分页，直接全量拉取医生名下所有状态为“待写”的病历，导致数据库慢查询。
* 2. 前端未使用 try-finally 包裹 loading 状态，网络异常或超时后 loading 无法重置。
*
* 修复方案：
* - 引入 PageHelper 分页查询，限制单次返回数据量（默认20条）。
* - 查询条件增加 doctor_id 与 visit_date 范围过滤，命中复合索引。
* - 标记 @Transactional(readOnly = true) 优化只读事务开销。
* 病历业务实现
*
* 修复 Bug #562：待写病历查询未分页导致全表扫描，加载时间超过2秒。
* 引入 PageHelper 严格限制查询范围，并优化 Mapper 仅返回列表展示所需字段。
