feat: V/R 유지보수 시스템 전환 및 대시보드 테이블 형태 완성

- V/R 시스템 완전 전환: WARRANTY/CONTRACT/INSPECTION → V(방문)/R(원격)
- 유지보수 대시보드 카드 → StandardDataTable 테이블 형태 전환
- "조회중..." 문제 해결: 백엔드 직접 필드 사용 (equipment_model, company_name)
- MaintenanceDto 신규 필드 추가: company_id, company_name, equipment_serial, equipment_model
- preloadEquipmentData 비활성화로 불필요한 equipment-history API 호출 제거
- CO-STAR 프레임워크 적용 및 CLAUDE.md v3.0 업데이트
- Flutter Analyze ERROR: 0 유지, 100% shadcn_ui 컴플라이언스
