feat: завершён этап 2 - Аутентификация Core Service

- Реализована JWT аутентификация с organization-scope
- Добавлено хеширование паролей через bcrypt
- Созданы репозитории для организаций и пользователей
- Реализован AuthService с бизнес-логикой
- Добавлен AuthMiddleware для проверки токенов
- Созданы handlers для регистрации и входа
- Обновлён API сервер для использования аутентификации

Готово для этапа 3 - API структура
