feat: добавлены анимации загрузки и переходов между разделами

Browse Source 
- Добавлен полноэкранный индикатор загрузки с размытием фона (LoadingOverlay)
- Реализован глобальный контекст загрузки для отслеживания переходов между страницами
- Добавлены плавные fade-анимации при переходах между страницами
- Реализованы поочередные (stagger) анимации для карточек:
  * Карточки дней на странице расписания
  * Карточки уроков внутри каждого дня
  * Карточки групп на главной странице
- Анимации работают на всех устройствах, включая мобильные
- Улучшен компонент Spinner с поддержкой разных размеров
- Исправлена ошибка гидратации с вложенными <li> элементами в навигации
- Оптимизированы задержки анимаций для более быстрого отображения контента
