WIP l FTP 캡처 (15): 412 에서 서버 주소 · 시작 폴더 칸의 예시 글이 잘리던 것 - 세 줄까지 (검토 대기)

캡처 시험 integration_test/windows_ftp_shot_test.dart (목록 · 추가 창 · 평문 경고 · 인증서 지문 창, 412/960 × ko/en/ja, release\test\shots_ftp_dd9e93b, 6 통과).
목록의 평문 ⚠ · 처음 값 FTPS · 평문 빨간 경고 · 지문 창은 세 언어 모두 문제 없음. 같은 꼴의 SFTP · SMB 창 예시 글도 잘리지만 이 브랜치에서는 FTP 만 고침.
