feat: 장비 관리 API 연동 구현

- Equipment 관련 DTO 모델 생성 (Request/Response/List/History/In/Out/IO)
- EquipmentRemoteDataSource 구현 (10개 API 엔드포인트)
- EquipmentService 비즈니스 로직 구현
- Controller를 ChangeNotifier 패턴으로 개선
- 장비 목록 화면에 Provider 패턴 및 무한 스크롤 적용
- 장비 입고 화면 API 연동 및 비동기 처리
- DI 컨테이너에 Equipment 관련 의존성 등록
- API/Mock 데이터 소스 전환 가능 (Feature Flag)
- API 통합 진행 상황 문서 업데이트
