🎨 Palette: 테이블 포커스 스타일을 :focus-visible로 개선하여 마우스 상호작용 개선

[seonghobae]

💡 What: python/fast_mlsirm/report.py의 포함된 CSS에서 .table-wrap:focus를 .table-wrap:focus-visible로 변경했습니다.
🎯 Why: 스크롤 가능한 테이블 컨테이너(tabindex="0")를 마우스로 클릭할 때마다 불필요한 윤곽선(outline)이 생겨 시각적인 방해를 주었습니다.
♿ Accessibility: 키보드 탐색을 위한 접근성 가이드를 충족하면서 동시에 마우스 사용자에게 부드러운 사용 경험을 제공합니다.
📚 Journal: .Jules/palette.md에 스크롤 가능한 컨테이너의 포커스 관리에 대한 UX/접근성 인사이트를 업데이트했습니다.

Superseded by lower-numbered #105. The :focus-visible report-table behavior is already consolidated there with regression coverage.
