/**
* 病历业务实现
*
* 修复 Bug #562待写病历列表加载超过2秒
* 根因原查询未强制分页且关联查询了完整病历内容CLOB/TEXT字段导致全表扫描与内存溢出风险。
* 修复方案
* 1. 强制启用 PageHelper 分页,限制单次返回数据量
* 2. 使用 @Transactional(readOnly = true) 优化只读查询性能
* 3. 仅查询列表展示所需的轻量字段PendingMedicalRecordDto避免加载完整病历正文
* 4. 增加耗时监控日志,便于后续性能追踪。
* 修复 Bug #562[门诊医生工作站-待写病历]数据加载时间超过2秒一直加载
*
* 关键修复点
* 1. 强制引入分页查询,避免全表扫描或一次性拉取海量数据导致 OOM/超时
* 2. 使用专用 Summary 查询方法,仅返回列表展示所需字段,剔除大文本 content 字段,降低 DB IO 与网络传输开销
* 3. 优化查询条件,确保走 doctor_id + status 联合索引
