/**
 * Auth-store: состояние текущего user'а + auth-actions через Sanctum SPA.
 *
 * Использование:
 *   const auth = useAuthStore();
 *   await auth.login({ email, password });        // редирект на /dashboard или /2fa
 *   await auth.fetchMe();                          // restore session при старте app
 *   if (auth.isAuthenticated) { ... }
 *   await auth.logout();
 *
 * Не входит:
 * - Persist user в localStorage (session-cookie держит state на backend; при
 *   page-reload `fetchMe()` восстанавливает user). Если cookie expired — 401
 *   и redirect на /login через Vue Router auth-guard.
