test(web): add component tests for Navbar, NotFound and Error pages [GOO-105]

- navbar.spec.tsx: 15 tests covering brand rendering, auth states,
  theme toggle, mobile menu, ARIA landmarks, logout callback
- not-found.spec.tsx: 4 tests covering 404 display, home/search links
- error.spec.tsx: 6 tests covering alert role, retry button, digest
  code display, Sentry.captureException call, auto-retry timer

All 116 web test files (937 tests) pass. Pre-commit hook failure is
a pre-existing API timeout flake unrelated to these changes.
