+"""add cookie manager menus
+
+「Cookie管理」一级菜单 + 二级「登录用户」/「登录网站」及各权限点，
+此前只在本地库里手工 INSERT 过，从未随迁移分发。
+
+由于 data/ 目录被 .gitignore 排除、部署环境数据库是独立 volume，
+只同步代码无法带上这些菜单行，导致线上后台看不到 Cookie 管理模块。
+
+本迁移以幂等方式补齐：
+- 记录不存在 → 插入
+- 已存在但 open_type 为空 → 补齐为 _iframe（兼容早期手工插入的数据）
+
+不依赖数据库方言的 UPSERT 语法，SQLite / MySQL 均可执行。
