test: 新增 admin-auth 完整測試套件

Unit Tests (30 tests):
- auth_service: LDAP 認證、管理員檢查
- page_registry: 頁面狀態管理、並發安全
- permissions: 權限檢查函數、裝飾器

Integration Tests (17 tests):
- 登入/登出路由
- 權限中介層
- Admin API
- Context Processor

E2E Tests (10 tests):
- 完整登入登出流程
- 頁面存取控制
- 頁面管理流程
- Portal 動態 tabs
- Session 持久性
- 安全性場景
