사용자 제공 (쿠팡상품코드, 제품코드) 매핑을 cupang_products.coupang_item_code
에 반영. product_code 정확 일치 행만 UPDATE, 변경 전 값은
_cpg_code_seed_backup 에 백업. cupang_products 에 없는 제품코드는
"미등록" 목록으로 출력만 하고 INSERT 하지 않는다.

+-- 사유: 사용자가 전달한 (쿠팡상품코드, 제품코드) 매핑 39건을
+--       cupang_products.coupang_item_code 에 반영한다.
+--
+-- 선행: scripts/sql/cupang_db_004_product_coupang_item_code.sql 적용 필요.
+--
+-- 안전: product_code 가 정확히 일치하는 행만 UPDATE 한다.
+--       (조건 없는 대량 UPDATE 아님. 삭제/DROP 없음)
+--       실행 전 현재 값을 _cpg_code_seed_backup 테이블에 남긴다.
+--       목록에 없는 제품은 건드리지 않는다.
+--
+-- 실행:
+--   docker exec -i postgres-db psql -U postgres -d cupang_db < /opt/www/main/scripts/sql/cupang_products_coupang_code_seed.sql
+--
+-- 되돌리기(백업 테이블이 남아 있을 때):
+--   UPDATE cupang_products p SET coupang_item_code = b.old_code
+--     FROM _cpg_code_seed_backup b WHERE b.id = p.id;
