fix: restore session from refresh token when access token is missing

When access token is absent from sessionStorage (tab reopen, page refresh)
but refresh token exists in localStorage, the request interceptor now
attempts token refresh before sending the request. Previously it would
send the request without Authorization header, causing 401 errors on
endpoints like /cabinet/auth/email/register.
