style: mono data font, compact actions, polish, favicon; slow status poll to 30s

- JetBrains Mono(로컬 동봉) → 저장소명/버전/패키지수/시각 등 영문·숫자 데이터에 적용
- 동기화/배포 버튼 컴팩트(btn-sm) + 액션 셀 높이 고정(row-action)으로 행 점프 제거
- 표 행 높이/hover, 요약 카드 강조(동기화중=blue, GPG통과=mint) + hover, 버튼 누름 피드백
- 연결 상태 폴링 10s → 30s
- SVG favicon (Toss blue 라운드 사각 + 스냅샷 레이어)
