크롤러 (utils/yakkok_crawler.py):
- yakkok.com에서 제품 검색 및 이미지 추출
- MSSQL 오늘 판매 품목 자동 조회
- base64 변환 후 SQLite 저장
- CLI 지원 (--today, --product)

DB (product_images.db):
- 바코드, 제품명, 이미지(base64), 상태 저장
- 크롤링 로그 테이블

어드민 페이지 (/admin/product-images):
- 이미지 목록/검색/필터
- 통계 (성공/실패/대기)
- 상세 보기/삭제
- 오늘 판매 제품 일괄 크롤링

API:
- GET /api/admin/product-images
- GET /api/admin/product-images/<barcode>
- POST /api/admin/product-images/crawl-today
