feat: завершён этап 1 - Фундамент Core Service

- Удалены зависимости: grpc, redis, prometheus - Упрощена конфигурация (Server, Database, JWT) - Создан логгер на основе logrus - Добавлено подключение к PostgreSQL - Создана миграция с базовыми таблицами - Обновлены модели с валидацией - Создан базовый API сервер с health check - Добавлен .env.example Готово для этапа 2 - Аутентификация

 ## 🚀 Этап 1: Фундамент (Недели 1-2)

 ### Шаг 1.1: Очистка и настройка проекта
- [ ] Удалить зависимости: `grpc`, `redis`, `prometheus`
- [ ] Обновить `go.mod` - оставить только необходимые пакеты
- [ ] Настроить структуру проекта согласно Go standards
- [ ] Добавить `.env` для конфигурации
