fix: HEIC 프리뷰 placeholder + 모바일 사진함 접근 허용

1. issue-report.js updatePhotoSlot: 브라우저가 <img> 로 렌더링 못하는
   포맷(HEIC 등) 감지해서 녹색 placeholder("📷 HEIC 첨부됨") 로 대체.
   photos[index] 데이터는 유지해서 업로드는 정상 동작 (서버 ImageMagick
   fallback 이 HEIC→JPEG 변환). 데스크톱 Chrome 에서 깨진 이미지 아이콘
   보이던 문제 해결.

2. m/management.html editPhotoInput: capture="environment" 제거.
   이 속성이 있으면 모바일에서 카메라 직접 호출만 되고 사진함 선택 UI 가
   나오지 않음. 관리함 사진 보충 시 기존 사진에서 고를 수 있어야 함.
