feat: 소프트 딜리트 기능 전면 구현 완료

## 주요 변경사항
- Company, Equipment, License, Warehouse Location 모든 화면에 소프트 딜리트 구현
- 관리자 권한으로 삭제된 데이터 조회 가능 (includeInactive 파라미터)
- 데이터 무결성 보장을 위한 논리 삭제 시스템 완성

## 기능 개선
- 각 리스트 컨트롤러에 toggleIncludeInactive() 메서드 추가
- UI에 "비활성 포함" 체크박스 추가 (관리자 전용)
- API 데이터소스에 includeInactive 파라미터 지원

## 문서 정리
- 불필요한 문서 파일 제거 및 재구성
- CLAUDE.md 프로젝트 상태 업데이트 (진행률 80%)
- 테스트 결과 문서화 (test20250812v01.md)

## UI 컴포넌트
- Equipment 화면 위젯 모듈화 (custom_dropdown_field, equipment_basic_info_section)
- 폼 유효성 검증 강화
