Fix/ai 요청 api 스트링 출력으로 변경

Summary by CodeRabbit

• Refactor
• AI 이미지 처리 결과를 바이트 전송·스토리지 업로드 대신 AI 서버의 최종 이미지 URL로 직접 반환하도록 전환해 결과 접근성을 높이고 응답 흐름을 단순화했습니다.
• 원본 파일명과 콘텐츠 타입을 보존해 전송 신뢰성을 개선했습니다.
• URL 기반 응답 검증으로 오류 메시지와 로그 가독성을 개선했습니다.
• 이미지 생성 후 결과 링크 수신이 더 일관되고 빠르게 제공됩니다.
• 기존 기능과 호환성을 유지했습니다.

Walkthrough

AI 서버 응답을 바이트 배열에서 URL DTO(AiResponseDTO)로 전환했다. WebClient 요청 본문을 MultipartBodyBuilder로 재구성하고, 응답 파이프라인을 DTO 기반으로 수정했다. 스토리지 업로드 단계는 제거되었으며, 새 DTO 클래스 AiResponseDTO가 추가되었다.

Changes

Cohort / File(s)	Summary
DTO 추가 src/main/java/.../avatar/image/AiResponseDTO.java	새 공개 DTO AiResponseDTO 추가. 필드: imageUrl(String). Lombok @Getter로 접근자 생성.
이미지 처리 서비스 리팩터링 src/main/java/.../avatar/image/service/ImageProcessingService.java	multipart 구성 방식을 MultipartBodyBuilder + ByteArrayResource로 교체. WebClient에서 BodyInserters.fromMultipartData(...) 사용 및 Content-Type: multipart/form-data 설정. 응답을 byte[] → AiResponseDTO로 변경하고 imageUrl 검증/반환. 스토리지 업로드 로직 제거. 로깅 문구와 예외 처리 경로를 URL 기반으로 조정. 보조 메서드 동작은 유지.

Poem

깡충, 깡충, 코드는 춤을 춘다
바이트 꾸러미 내려놓고 URL만 쥔다
토끼는 수신 확인, DTO에 미소 번진다
멀티파트 다듬고, 응답 길만 따른다
오늘의 한 입: imageUrl—달처럼 반짝인다 🌕🐇
