feat(portal-shell): wire AppFrame + navigation + permission filter (P1-1)

实现 ARCHITECTURE.md §10 P1-1：
- 新增 src/shared/lib/navigation.ts：27 项静态导航注册表，
  按 teacher/student/parent/admin 四角色分区，group 字段用于角色过滤
- 新增 src/app/shell/layout.tsx：RSC AppFrame，从 headers() 读取
  middleware 注入的身份头，batchCheckRoutePermission 按位图二次过滤
- 新增 src/shared/components/layout/user-menu.tsx：顶部用户菜单，
  显示 userId + role，登出 POST /api/auth/logout
- 新增 src/shared/lib/__tests__/navigation.test.ts：P1-1 验收单测
  （7 用例：href 登记一致性 + 4 角色隔离 + 权限检查）
- 修改 src/shared/lib/route-permissions.ts：补全 7 个列表页根路由
  的 EXACT 登记（/shell/admin/announcements、/shell/admin/classes、
  /shell/teacher/exams 等），与 PREFIX 表互补避免 catch-all 拒绝

验收：
- vitest run navigation → 7/7 passed
- tsc --noEmit 通过；eslint（5 文件）通过

回填 ARCHITECTURE.md §10 P1-1 状态为 ✅，附验收证据。
