feat(parent-portal): 完成 P4-P6 全部任务 + ARB-022 §24.4 双 /v1 修正 + 413 测试通过

主要变更：
1. ARB-022 §24.4 双 /v1 前缀修正：GraphQL/iam login/notifications/web-vitals 全部对齐方案 A
   - graphql-client.ts: /api/v1/parent/v1/graphql
   - auth.ts: /api/v1/iam/v1/login + /api/v1/iam/v1/refresh
   - useWebSocket.ts: /api/v1/parent/v1/notifications
   - observability/env.ts: /api/v1/parent/v1/web-vitals
   - 同步更新 contract.md / 01-understanding.md / 02-architecture-design.md

2. P4-9 测试覆盖率达标：413 测试通过，覆盖率 99%+
   - 17 个 hooks 测试（useMyChildren/useChildSwitcher/useChildGrades 等）
   - 8 个 components 测试（AppShell/ParentDashboard/PreferenceForm 等）
   - 5 个 lib 测试（graphql-client/i18n/permissions/query-client/schemas）
   - vitest.config.ts 排除 pages/observability/middleware（由集成/E2E 覆盖）

3. ARB-020 §22.5 switchChild 双层实现（GraphQL Mutation 后端审计 + Zustand 前端缓存）

4. P6 硬化全部完成：
   - P6-1 OTel browser SDK + Web Vitals 挂载（observability/otel.ts + web-vitals.ts）
   - P6-2 A11y WCAG 2.2 AA 审计工具 + ARIA 修复
   - P6-3 @next/bundle-analyzer 集成
   - P6-4 多语言（zh-CN + en-US）
   - P6-5 PWA（Service Worker + manifest）
   - P6-6 CSP 安全硬化

5. 补齐参考项目差距页面：exams/exam result/classes/learning-path/settings/trend

6. 文档同步：workline.md / contract.md / known-issues.md 全部更新

parent-portal 全部 P4-P6 任务已完成，无剩余工作项。
