feat(frontend): Phase 2/3 hardening release

Roadmap P0
- Ship /logo.svg fallback and rewire asset references (superseded later by
  the project-manager PNG in a separate commit).

Roadmap P1
- Response envelope alignment ({items,total,page,size}) across services
  and query hooks.
- Approval/ticket UX updates tied to the new backend rollback semantics.

Roadmap P2
- React.lazy + Vite manualChunks to split vendor-radix/charts/icons/forms
  from the main bundle and cut initial JS.
- Fix the 181 tsc errors (PaginationParams class + per-service generics).
- Auto-refresh flow for JWT refresh tokens wired into api-client.ts.

Roadmap P3
- i18n: i18next + language detector, en/ar locales, RTL auto-switch,
  LanguageToggle component in RoleLayout and AdminLmsLayout.
- GDPR: PrivacyCenter page for data export and right-to-erasure, backed
  by gdpr.service.ts; logout via AuthContext after erasure.
- Human-in-the-loop exam review UI: admin ExamReviewQueue + ExamReviewDetail
  pages, useExamReview hooks, exam-review.service.ts.
- AI quality loop: AIPromptEditor (versioning + render preview),
  AIFeedbackButtons for students, AIFeedbackTriage admin page, dedicated
  services, hooks, and types.
- Dark mode: ThemeProvider + ThemeToggle + chart color tokens.
- Accessibility: DialogDescription on every DialogContent; alert-dialog
  and sheet updates.
- Retire dead pages: ExamPage marketing, Index, ProfilePage import.
- Playwright e2e scaffolding: playwright.config.ts + e2e/login.spec.ts
  smoke tests, npm scripts test:e2e / test:e2e:install.
