test(web): increase frontend test coverage to ~70% page coverage

- Fix vitest config to include [locale] directory tests (was excluded)
- Fix register.spec.tsx: use getByRole('heading') to avoid duplicate text match
- Fix search.spec.tsx: add QueryClientProvider wrapper and mock saved searches hook
- Add 12 new page test files covering dashboard, admin, public, and OAuth pages:
  - dashboard (main, profile, payments, subscription, KYC)
  - admin (dashboard, users)
  - public (landing, pricing)
  - analytics
  - OAuth callbacks (Google, Zalo)
- 29 test files, 174 tests, 16/23 pages covered (69.6%)
