test(web): add Vitest tests for search, auth, public, and admin layouts
- SearchLayout: verifies children pass-through (3 tests)
- AuthLayout: verifies role=main, #main-content, max-w-md centering (5 tests)
- PublicLayout: verifies navbar, ticker strip, footer, compare bar, #main-content (8 tests)
- AdminLayout: verifies sidebar nav, auth guard, loading state, logout, mobile toggle (10 tests)
All 156 web test files pass (1157 total web tests). Pre-existing API test
failures in unrelated modules (auth OTP handler, projects, search indexer,
admin settings encryption) are outside scope of this task.
