✨ [FEAT] 평면도 부스 위치 AI 자동 배치 제안 기능 - #90

Conversation
Gemini Vision API로 업로드된 평면도 이미지에서 부스 사각형을 검출해 좌표를 제안한다. 라벨 오독·비결정성 위험이 실측으로 확인되어 좌표는 저장하지 않고 "제안"만 반환하며, 관리자가 확인 후 기존 좌표 저장 API로 직접 확정해야 한다.

- Around line 220-248: Update the automatic layout request flow around
suggestAutoLayout and selectMap so it captures the selected map generation at
request start and verifies that generation after the response, aborting before
applying additions when the selected map has changed. Use eventGenerationRef
only if it is incremented by selectMap; otherwise add or reuse a map-specific
generation/ref that selectMap updates whenever selectedMapId or positions
change, while preserving the existing stale-request guard.

평면도 세대를 자동 배치 요청에 포함하세요.
selectMap은 selectedMapId와 positions만 변경하고 eventGenerationRef는 변경하지 않습니다. 평면도 A에서 요청한 뒤 B를 선택하면 A의 제안이 B의 positions에 추가될 수 있습니다. 이후 handleSavePositions가 해당 좌표를 B에 저장할 수 있습니다. 요청 시작 시 평면도 세대를 저장하고, 응답 후 세대가 다르면 중단하세요.

CodeRabbit 리뷰 지적사항 반영. handleAutoLayout이 응답을 기다리는 동안 관리자가 다른 평면도를 선택하면, eventGenerationRef만으로는 감지되지 않아 늦게 도착한 제안이 새로 선택된 맵의 positions에 그대로 합쳐졌다. selectMap이 갱신하는 mapSelectionGenerationRef로 같은 맵을 계속 보고 있는지 함께 확인하도록 수정.

📄 작업 내용
줄이기 위해, Gemini Vision(
gemini-3.1-flash-lite,responseSchema구조화 출력)으로 평면도 이미지에서 부스 사각형을 검출해 좌표를
제안하는 기능을 추가했다.
저장하지 않고 "제안"만 반환한다 — 밀집한 도면에서 라벨 오독, 그리고
같은 이미지도 호출마다 결과가 달라지는 비결정성이 실측으로 확인되어,
최종 저장은 관리자가 기존
upsertPositionsAPI로 직접 확정해야 한다.자동 반영하되 이미 배치됐거나 다른 층에 배치된 부스는 건너뛴다.
@Transactional이 최대 45초 걸리는 외부 API 호출 동안 DB 커넥션을붙잡고 있던 문제 (커넥션 풀 고갈 위험)
box_2d에 null을 섞어 반환하면 NPE로 요청 전체가 실패하던문제

💬 리뷰어에게
GEMINI_API_KEY가 필요하며, 배포 환경 시크릿 동기화는 이미 dev에 반영된fix/gemini-api-key-secret-syncPR에서 처리됨."제안"으로만 동작하고 저장은 관리자가 명시적으로 확정해야 하는 구조로
설계했다.
