+/**
+ * 门诊病历数据访问层
+ *
+ * 修复 Bug #562：待写病历列表加载缓慢（>2s）
+ * 根因分析：
+ *   原实现使用 `SELECT *` 查询病历表，导致包含大文本字段（如 `record_content`, `history`, `diagnosis_detail`）
+ *   的全量数据被加载至内存并进行 JSON 序列化，造成网络 IO 与 CPU 耗时过长。
+ * 修复方案：
+ *   1. 显式指定列表视图所需字段，剔除大文本列，仅返回基础展示信息；
+ *   2. 增加 `ORDER BY create_time DESC` 与 `LIMIT` 限制，避免全表扫描与过量数据返回；
+ *   3. 建议 DBA 配合创建复合索引：`CREATE INDEX idx_medical_record_doctor_status_time ON medical_record(doctor_id, status, create_time DESC);`
