Replaced focusable span wrappers around disabled buttons with native `<button>` and `<Button>` components utilizing `aria-disabled="true"` and `tabIndex={0}`. Added correct Tailwind classes for visual consistency. Updated tests accordingly.

Subject: [PATCH 2/2] =?UTF-8?q?=F0=9F=8E=A8=20Palette:=20[UX=20improvement?=
 =?UTF-8?q?]=20Fix=20App.tsx=20missing=20test=20coverage?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Added a unit test trigger to fulfill the 100% code coverage requirement in `App.test.tsx` by explicitly clicking the disabled Settings and Help buttons which now contain inline `onClick` handlers.

💡 What: 인라인 `onClick={(e) => e.preventDefault()}` 핸들러를 위한 테스트 커버리지를 App.test.tsx에 추가했습니다.
🎯 Why: PR 빌드 파이프라인에서 App.tsx 내 특정 줄(559, 569)이 실행되지 않았다는 코드 커버리지 부족 오류가 발생했습니다.
📸 Before/After: 설정 및 도움말 버튼이 이제 올바르게 비활성화됨을 증명하는 클릭 테스트 코드가 실행됩니다.
♿ Accessibility: 접근성 향상을 위한 DOM 구조 간소화가 지속적으로 커버리지와 호환되게 했습니다.
