Оптимизирована производительность React компонентов с помощью мемоизации

КРИТИЧНЫЕ КОМПОНЕНТЫ ОПТИМИЗИРОВАНЫ:
• AdminDashboard (346 kB) - добавлены React.memo, useCallback, useMemo
• SellerStatisticsDashboard (329 kB) - мемоизация кэша и callback функций
• CreateSupplyPage (276 kB) - оптимизированы вычисления и обработчики
• EmployeesDashboard (268 kB) - мемоизация списков и функций
• SalesTab + AdvertisingTab - React.memo обертка

ТЕХНИЧЕСКИЕ УЛУЧШЕНИЯ:
✅ React.memo() для предотвращения лишних рендеров
✅ useMemo() для тяжелых вычислений
✅ useCallback() для стабильных ссылок на функции
✅ Мемоизация фильтрации и сортировки списков
✅ Оптимизация пропсов в компонентах-контейнерах

РЕЗУЛЬТАТЫ:
• Все компоненты успешно компилируются
• Линтер проходит без критических ошибок
• Сохранена вся функциональность
• Улучшена производительность рендеринга
• Снижена нагрузка на React дерево
