데이터 불러오고 매핑하기 클릭 시 400 발생.
원인: 프론트는 camelCase (apiUrl/endpoint/method/apiKey/dataArrayPath/paramType/...)
로 body 를 보내는데 백엔드는 snake_case (api_url/endpoint/method/api_key/...) 키로 읽음.
다른 service 진입점 (updateBatchConfig / executeBatchConfig 등) 은 convertCamelToSnake
를 호출해서 자동 변환하는데 previewRestApiData 만 빠져있어 isBlank(apiUrl)=true 가
되며 IllegalArgumentException → 400.

수정: previewRestApiData 진입부에 convertCamelToSnake(body) 한 줄 추가.
