/**
 * Full login/logout lifecycle, auth state transitions, and UI gating tests.
 *
 * Scenarios covered:
 * - SCN-login-programmatic: Programmatic login sets correct app state
 * - SCN-logout-clears-state: Logout resets auth state and hides gated UI
 * - SCN-login-logout-cycle: Repeated login/logout cycles maintain consistency
 * - SCN-auth-gated-ui: Protected UI elements appear/disappear based on auth
 * - SCN-login-modal-open-close: Login modal opens and closes correctly
 * - SCN-login-provider-selection: Provider buttons are rendered and selectable
 * - SCN-auth-persists-navigation: Auth state survives in-page navigation
 * - SCN-concurrent-state-check: App state inspection is consistent after auth
