feat(t10-admin): 管理员体系前端——应用设置双 tab+单表单管理员+选人组件移植

- AppSettings.vue 应用设置页（基础/字典两 tab）；修复 P86：Tabs 写 :value 而受控 prop 是 modelValue，致 ?tab=dicts 深链静默失效，改后深链实拍生效
- UserCheckModal.vue 自 notice 移植（view-ui-plus+ztree，sources 注入式数据源）；public/libs 收录 jquery+ztree 本地件（index.html 引用）
- api/module/admin.ts + mock/adminapi.ts + types/admin.ts；AdminListPanel/FormAdminModal 组件
- routes/menuNav/menuRoute/modulePerms 适配管理员菜单与权限位；tree-icon 图标资源

+/**
+ * 管理员两表的本地 Mock（vite-plugin-mock，仅 `npm run dev:mock` 生效）。
+ *
+ * 用途与背景同 baseapi.ts：本机没有 UserBase 授权数据（执行手册 §5 P1 降级取证先例），
+ * 角色设置 tab 与「表单管理员」弹窗的两表 CRUD 往返只能在 mock 里实拍。
+ * 桩刻意把后端三条规则也演一遍，好让冒烟脚本能断言到"前端没有把规则写丢"：
+ * ① 重复添加幂等（不重复建行、不报错）；② 校级管理员删到剩 0 拒；③ 写操作回全量列表。
