/**
 * Reset the Auth manager's default guard and cached guard instances back to
 * the 'web' SessionGuard.
 *
 * Necessary because auth:sanctum middleware calls Auth::shouldUse('sanctum')
 * on every successfully-authenticated request, which permanently changes
 * config('auth.defaults.guard') to 'sanctum' in the shared test application
 * instance. Laravel feature tests reuse the same $this->app between HTTP calls,
 * so this pollution persists across requests. Any subsequent call to
 * Auth::login() (which internally calls Auth::guard()->login()) then resolves
 * to the Sanctum RequestGuard — which has no login() method — and throws a
 * BadMethodCallException.
 *
 * The reset must happen *before* any request whose controller calls Auth::login()
 * without an explicit guard argument (i.e. login and 2fa/verify routes).
