Subject: [PATCH] op/datapack: add painting_variant JSON zip export button
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

데이터팩 수정 페이지에 "이미지.zip 출력" 버튼과 크기 입력(기본 4, 1~16)
을 추가. 누르면 GET /op/datapack/:key/images-zip?size=N 으로 음악 개수만큼
cover_NN.json (asset_id, width=size, height=size, title, author) 을 zip 으로
스트리밍해서 내려준다. 사용자가 맵 데이터팩의 data/musicquiz/painting_variant/
에 그대로 풀어 넣을 수 있다.
