### 🔧 Redis Connection Pool Fix - **🐛 Fixed "max number of clients reached" error**: Исправлена критическая ошибка превышения лимита соединений Redis - Добавлен `aioredis.ConnectionPool` с ограничением `max_connections=20` для 5 микросервисов - Реализовано переиспользование соединений вместо создания новых для каждого запроса - Добавлено правильное закрытие connection pool при shutdown приложения - Улучшена обработка ошибок соединения с автоматическим переподключением - **📊 Health Monitoring**: Добавлен `/health` endpoint для мониторинга состояния Redis - Отображает количество активных соединений, использование памяти, версию Redis - Помогает диагностировать проблемы с соединениями в production - **🔄 Connection Management**: Оптимизировано управление соединениями - Один connection pool для всех операций Redis - Автоматическое переподключение при потере соединения - Корректное закрытие всех соединений при остановке приложения ### 🧪 TypeScript Warnings Fix - **🏷️ Type Annotations**: Добавлены явные типы для устранения implicit `any` ошибок - Исправлены типы в `RolesModal.tsx` для параметров `roleName` и `r` - Устранены все TypeScript warnings в admin panel ### 🚀 CI/CD Improvements - **⚡ Mypy Optimization**: Исправлена проблема OOM (exit status 137) в CI - Оптимизирован `mypy.ini` с исключением тяжелых зависимостей - Добавлен `dmypy` с fallback на обычный `mypy` - Ограничена область проверки типов только критичными модулями - Добавлена проверка доступной памяти перед запуском mypy - **🐳 Docker Build**: Исправлены проблемы с PyTorch зависимостями - Увеличен `UV_HTTP_TIMEOUT=300` для загрузки больших пакетов - Установлен `TORCH_CUDA_AVAILABLE=0` для предотвращения CUDA зависимостей - Упрощены зависимости PyTorch в `pyproject.toml` для совместимости с Python 3.13
