Исправлено форматирование SQL-запроса в функции sitemap, добавлена обработка исключений в функциях detail_vin и search для ограничения частоты запросов. Добавлен новый маршрут для отображения страницы ограничения частоты запросов. Обновлен шаблон rate_limit.html с добавлением QR-кода для Telegram-бота.
