"""人员管理接口集成测试（需要 MySQL 与 Redis）。

守的是人员档案的引用完整性 —— 岗位与直属经理是 M3 核算取公式模板与
经理聚合展开的锚点，悬空引用或环引用会让核算取不到公式、聚合死循环；
删除保护缺失会留下悬空的 manager_id 与客户归属，历史核算无法回溯到人；
辐射区域与拓展计划若把「全量替换」做成了追加，编辑一次就翻倍一份脏数据。

运行前置：``docker compose -f docker/docker-compose.dev.yml up -d``

数据卫生：人员姓名一律 ``t_`` 前缀，由 conftest 兜底清理；仅「删除」
语义的用例自验 DELETE 端点。
