为什么：auth_system 的 11 个子模块此前构成一个强连通分量——db.py 与 backup.py
为了「动态读取路径常量」而在模块级 `import auth_system`（包自身），而包 __init__
又再导出这两个子模块的全部符号，互相指成环。
这个环当前并不崩（实测 8/8 种导入姿势全通过），它的代价是**双绑定**：
`auth_system.DB_PATH is auth_system.db.DB_PATH` 初始为 True，但只 patch 其一
另一处不跟随。于是测试不得不把 4 个路径常量**两处都 patch**
（setattr(auth,...) + setattr(db,...)）——而漏 patch 的后果是静默写生产库，
commit fc7fc21 修的那次「黄金测试写进生产库」正是这么来的。
改法：让路径常量回归**模块属性单一来源**。
- db.py：删掉 `import auth_system`，内部改用本模块常量（DATA_DIR / DB_PATH /
SECRET_KEY_PATH）。这些常量本就定义在本模块，绕道包属性纯属多余。
- backup.py：改用 `import auth_system.db as db` 做模块限定访问，路径走
db.BACKUP_DIR / db.DB_PATH——保留动态读取能力，来源从「包属性」换成
「db 模块」，与唯一来源一致。
注意**不能**写成 `from . import db`：该形式在静态图里同时指向包本身与子模块，
会把这个环重新连上（实测确实如此，SCC 从 11 降到 2 就卡住了）。
- admin_site.py：5 处 `auth.DB_PATH` / `auth.BACKUP_DIR`（auth 是包别名）同样
改为经 db 模块访问。**这处不修就会出事**——它读的是包属性快照，而测试已改为
patch db 模块，于是备份上传会静默落到生产 data/backups/（本次实测真的发生了，
2 个 upload_*.db 已清理，副本留在临时目录）。
- 测试：7 个文件的 patch 目标从包属性迁到 auth_system.db.*。
- __init__.py：补注释说明这些常量在此只是 import 快照，禁止经包属性重定向。
验证：
- Tarjan 重算：非平凡强连通分量 11 → **0**（import 图已是 DAG）
- AST 全仓扫描：经包属性访问路径常量的点 **0 处残留**
- 行为：子进程内 patch auth_system.db.* 后，get_conn 连的库 / create_backup
落盘目录 / get_secret_key 目标路径**三者全部跟随**
- 导入姿势回归 8/8 通过
