🎨 Palette: [UX improvement] Date Range Picker 컴포넌트 접근성 개선

[seonghobae]

💡 What: DateRangePicker의 프리셋 버튼(7d, 30d 등)에 스크린 리더를 위한 명확한 라벨(aria-label)과 활성화 상태(aria-pressed)를 추가하고, 키보드 사용자들을 위한 포커스 스타일(focus-visible)을 개선했습니다. 덧붙여 해당 컴포넌트 동작에 대한 완벽한 테스트 코드를 추가했습니다.

🎯 Why: 기존의 프리셋 버튼들은 시각적으로만 구분되어 있어 스크린 리더 환경이나 키보드 내비게이션(Tab 이동)만 사용할 경우 현재 어떤 필터가 적용되어 있는지, 어떤 버튼이 선택되었는지 명확히 인지하기 어려웠기 때문입니다. 테스트 코드의 경우 지침에 따라 신뢰성 확보를 위해 도입했습니다.

📸 Before/After:

• 스크린 리더 음성: (기존) "7d 버튼" -> (개선) "지난 7일 버튼, 눌림"
• 포커스: (기존) 눈에 잘 띄지 않음 -> (개선) 명확한 링 형태의 포커스 표시

♿ Accessibility:

• aria-label을 통해 의미론적인 텍스트 제공
• aria-pressed를 통해 토글 버튼의 현재 상태 제공
• Tailwind focus-visible:ring-2를 통해 키보드 사용 시 시각적 인지 향상

Closing as superseded during org-wide PR triage. Keeping #213 as the canonical PR for the same overlapping topic: date range picker/accessibility. This PR is stale/conflicted or has review blockers, so retaining one current PR reduces duplicated review and merge conflict work.
