refactor: 프로젝트 정리 및 최적화 (미사용 파일 제거, 코드 중복 제거, 정적 이미지 빌드 경로 수정)

- 미사용 목업 파일(dummyData.ts, realServerData.ts, server_data.json) 및 중복 기획서 제거

- excelHandler.ts 내 미사용 대용량 엑셀 처리 함수들을 삭제하여 xlsx 의존성 제거 및 클라이언트 빌드 크기 최적화

- ListFactory.ts와 utils.ts 간에 중복으로 존재하던 calculatePcScoreDeductive 함수를 하나로 일원화

- 기획서 및 계획 문서들을 docs/plans/ 하위 폴더로 이동하여 프로젝트 루트 정리

- 정적 이미지 폴더(img/)를 public/img/로 이동하여 프로덕션 빌드 시 로고 및 장비 사진 엑박 오류 해결
