🎨 Palette: [UX improvement] 향상된 접근성을 위한 비활성화 버튼 초점 유지

[seonghobae]

💡 What: '공유 및 내보내기' 모달의 '접근 관리' 버튼에서 네이티브 disabled 속성을 제거하고 aria-disabled="true"와 시각적 비활성 스타일을 적용했습니다.
🎯 Why: 네이티브 disabled 버튼은 탭 순서에서 제외되어 스크린 리더 사용자가 해당 버튼에 연결된 aria-describedby 힌트("접근 권한 관리는 프로젝트 권한 설정에서 처리합니다.")를 읽을 수 없는 접근성 문제가 있었습니다.
📸 Before/After: 시각적 변경 사항 없음 (기존 비활성 스타일 유지됨)
♿ Accessibility: 비활성화된 버튼에 키보드 포커스가 가능해져 스크린 리더가 버튼의 비활성 상태 이유를 설명하는 힌트 텍스트를 정상적으로 읽어줍니다.

Devin Review found 3 potential issues.

🟡 Changelog not updated for user-visible change

CLAUDE.md and CONTRIBUTING.md require user-visible frontend changes to be recorded in CHANGELOG.md and frontend/CHANGELOG.md. This PR alters the '접근 관리' button behavior and its visual style (opacity 0.9→0.6, cursor, color) but adds no entry to either file.

Prompt for agents

This PR makes a user-visible frontend change (the '접근 관리' disabled button now uses aria-disabled and its visual style changed) but does not update the changelogs. Per CLAUDE.md and CONTRIBUTING.md, add a corresponding entry under the [Unreleased] section of both CHANGELOG.md and frontend/CHANGELOG.md (in Korean) describing the accessibility improvement to the disabled button focus/hint behavior.

📝 Info: aria-disabled button remains activatable

Switching from native disabled to aria-disabled leaves the button focusable and clickable; onClick={(e) => e.preventDefault()} is a no-op since the button has no real action. Harmless now, but any future handler must itself early-return, as aria-disabled does not block activation.

📝 Info: Visual change despite 'no visual change' claim

The PR description states no visual change, but .exportModal__disabledHintButton opacity drops from 0.9 to 0.6 (plus new cursor/color), so the button appears more faded than before.
