UI: стиль главной страницы, новый лого и favicon

- Заменён логотип на новый (MONT Group of companies)
- Favicon взят с stend.4mont.ru, перенесён в static/
- Лого фиксировано в левом верхнем углу (position:fixed), уменьшено на 30%
- Добавлена кнопка «Инфраструктурный полигон МОНТ» → stend.4mont.ru
- Градиентный текст h1, анимация fadeUp при загрузке
- Акцент-полоски в заголовках карточек, hover-эффекты на row-card
- Статистика переведена на таблетки (stat-pill)
- Счётчики-бейджи рядом с «Вендоры» и «Категории»
- Кастомный скроллбар в панелях чипов
- Улучшены теги продуктов, кнопка сброса фильтров
