feat(v027): SettingsPage scaffold — 4 섹션 placeholder + 돌아가기

v027 plan Task 7. zustand store 의 showSettings 를 사용하는 첫 컴포넌트.
4 섹션 (AI 제공자/자동 실행/백업·복원/정보) placeholder 와 헤더 + 돌아가기 버튼만.
실 콘텐츠는 후속 Task 8-11 에서 채움.

테스트 인프라 동시 추가 (v027 의 첫 React 컴포넌트 테스트):
- @testing-library/react + @testing-library/jest-dom + jsdom devDep 추가
- vitest.config: plugin-react 적용, include 에 .test.tsx 포함
- 환경 분리는 per-file `// @vitest-environment jsdom` directive 로 처리
  (vitest 4.x 에서 environmentMatchGlobs 미지원 — 기존 .ts 단위 테스트는 node env 유지)
