refactor: Clean Architecture 적용 및 코드베이스 전면 리팩토링

## 주요 변경사항

### 아키텍처 개선
- Clean Architecture 패턴 적용 (Domain, Data, Presentation 레이어 분리)
- Use Case 패턴 도입으로 비즈니스 로직 캡슐화
- Repository 패턴으로 데이터 접근 추상화
- 의존성 주입 구조 개선

### 상태 관리 최적화
- 모든 Controller에서 불필요한 상태 관리 로직 제거
- 페이지네이션 로직 통일 및 간소화
- 에러 처리 로직 개선 (에러 메시지 한글화)
- 로딩 상태 관리 최적화

### Mock 서비스 제거
- MockDataService 완전 제거
- 모든 화면을 실제 API 전용으로 전환
- 불필요한 Mock 관련 코드 정리

### UI/UX 개선
- Overview 화면 대시보드 기능 강화
- 라이선스 만료 알림 위젯 추가
- 사이드바 네비게이션 개선
- 일관된 UI 컴포넌트 사용

### 코드 품질
- 중복 코드 제거 및 함수 추출
- 파일별 책임 분리 명확화
- 테스트 코드 업데이트

## 영향 범위
- 모든 화면의 Controller 리팩토링
- API 통신 레이어 구조 개선
- 에러 처리 및 로깅 시스템 개선

## 향후 계획
- 단위 테스트 커버리지 확대
- 통합 테스트 시나리오 추가
- 성능 모니터링 도구 통합
