- auto_build 시그니처에 card_cuts 폼 필드 추가
- JSON 배열 문자열 파싱 (값 깨져도 빌드 계속)
- job dict에 저장 후 process_paste 호출에 전달
- bool 필터링 강화: JSON true/false가 정수로 둔갑하지 않도록

이유: JSON의 true/false가 Python bool로 파싱되는데, bool이 int의 서브클래스라
isinstance(v, int)를 통과해 컷 인덱스 1/0으로 대신 쓰이는 문제 해결.
capcut_agent/recommend.py 패턴과 일관성 있음.
