fix(pop-card-list): 원본 컴포넌트 선택 안 되는 문제 수정

- CartListModeConfig에 sourceComponentId 추가
- cartType이 빈 문자열인 경우 componentId로 매칭
- Select value: sourceComponentId 기반 안정적 매칭
- 런타임: sourceComponentId > cartType > 첫 번째 순으로 폴백

원인: 4160 화면의 cartAction에 cartType 미설정 -> 빈 문자열 ->
Select 저장 시 undefined 순환 -> 선택 불가
