fix(auth): не выкидывать пользователя при сетевой ошибке refresh, access token 30 дней

- queryClient: refreshSession возвращает reason (network/unauthorized);
  при network-ошибке не делаем logout, а бросаем network_error_during_refresh.
- useAuth: checkAuth и refreshUser не сбрасывают сессию при network-ошибке
  во время refresh, переводят в офлайн-режим.
- auth.service: remember берётся из сессии, race tolerance 5 минут.
- access token lifetime унифицирован до 30 дней по умолчанию, cookie maxAge
  теперь совпадает с JWT expiry (было 15 минут fallback).
