feat: завершён этап 3 - API структура Core Service

- Созданы репозитории для locations, items, operations - Реализованы сервисы с бизнес-логикой - Созданы HTTP handlers для всех API endpoints - Добавлена функция GetClaims в middleware - Обновлён server.go для интеграции всех компонентов - Поддержка JSON полей в PostgreSQL - Organization-scope фильтрация во всех операциях - Валидация запросов через validator Готово для этапа 4 - Шаблоны помещений
