feat: DB V3 정규화 및 용도 기반 동적 UI 구현

- 백엔드: asset_core(마스터), asset_spec(사양), asset_volume(스토리지), asset_location(위치), asset_network(네트워크/원격) 5개 테이블로 V3 정규화 완료

- 백엔드: /api/assets/master 단일 엔드포인트로 통합 및 서브쿼리 최적화를 통한 UI 하위 호환성 유지

- 백엔드: 저장 로직(save) V3 스키마 분산 저장 및 cascade 기반 삭제 로직 적용

- 프론트엔드(HWModal): '현 용도(current_role)' 필드 추가 및 서버/개인용에 따른 네트워크/위치 섹션 동적 렌더링 구현

- 프론트엔드(state): 분산된 API 호출을 단일 호출로 통합하여 렌더링 성능 최적화

- 레거시 백업 파일 및 불필요한 구형 테이블 완벽 정리 완료
