refactor: Repository 패턴 적용 및 Clean Architecture 완성

## 주요 변경사항

### 🏗️ Architecture
- Repository 패턴 전면 도입 (인터페이스/구현체 분리)
- Domain Layer에 Repository 인터페이스 정의
- Data Layer에 Repository 구현체 배치
- UseCase 의존성을 Service에서 Repository로 전환

### 📦 Dependency Injection
- GetIt 기반 DI Container 재구성 (lib/injection_container.dart)
- Repository 인터페이스와 구현체 등록
- Service와 Repository 공존 (마이그레이션 기간)

### 🔄 Migration Status
완료:
- License 모듈 (6개 UseCase)
- Warehouse Location 모듈 (5개 UseCase)

진행중:
- Auth 모듈 (2/5 UseCase)
- Company 모듈 (1/6 UseCase)

대기:
- User 모듈 (7개 UseCase)
- Equipment 모듈 (4개 UseCase)

### 🎯 Controller 통합
- 중복 Controller 제거 (with_usecase 버전)
- 단일 Controller로 통합
- UseCase 패턴 직접 적용

### 🧹 코드 정리
- 임시 파일 제거 (test_*.md, task.md)
- Node.js 아티팩트 제거 (package.json)
- 불필요한 테스트 파일 정리

### ✅ 테스트 개선
- Real API 중심 테스트 구조
- Mock 제거, 실제 API 엔드포인트 사용
- 통합 테스트 프레임워크 강화

## 기술적 영향
- 의존성 역전 원칙 적용
- 레이어 간 결합도 감소
- 테스트 용이성 향상
- 확장성 및 유지보수성 개선

## 다음 단계
1. User/Equipment 모듈 Repository 마이그레이션
2. Service Layer 점진적 제거
3. 캐싱 전략 구현
4. 성능 최적화
