feat: 관리자 페이지 사용자 상세 이력 조회 기능 추가

- Flask 백엔드에 /admin/user/<user_id> API 엔드포인트 추가
- SQLite에서 사용자 정보, 마일리지 이력, 구매 이력 조회
- MSSQL에서 각 거래별 상품 상세 조회 (SALE_SUB + CD_GOODS JOIN)
- "첫번째상품명 외 N개" 형식 요약 생성

- admin.html 사용자 테이블에 클릭 이벤트 추가
- 사용자 상세 모달 UI 구현 (탭 + 아코디언)
- 탭: 구매 이력 / 적립 이력 분리 표시
- 아코디언: 각 구매 건 클릭 시 상품 목록 펼침/접기
- CSS 스타일 추가 (아코디언 애니메이션, 테이블 호버 효과)
