[E2E] Fix Session Expiration Test Failures

Summary

3 tests in tests/core/authentication.spec.ts are failing due to difficulty simulating session expiration scenarios.

Failing Tests

1. should clear authentication cookies on logout (line 219)
2. should redirect to login when session expires (line 310)
3. should handle 401 response gracefully (line 335)

Root Cause

These tests require either:

1. Backend API endpoint to invalidate sessions programmatically
2. Playwright route interception to mock 401 responses

Proposed Solution

Add a route interception utility in tests/utils/route-mocks.ts:

export async function mockAuthenticationFailure(page: Page) {
  await page.route('**/api/v1/**', route => {
    route.fulfill({ status: 401, body: JSON.stringify({ error: 'Unauthorized' }) });
  });
}

Priority

Medium - Edge case handling, does not block core functionality testing
