feat: 프론트 인증 연동 (소셜 로그인 + Bearer 세션)

- 로그인 화면: 구글(GIS) 버튼 + 애플 버튼 + 개발용 로그인(local)
- 인증 스토어(Pinia): 토큰 복구/로그인/로그아웃, 회원 티어를 광고·매칭 제어에 반영
- HTTP 클라이언트: Authorization Bearer 자동 첨부, 401 시 토큰 폐기 후 로그인 이동
- 라우터 가드: 미로그인 시 보호 경로 → /login (소셜 로그인 전용 앱)
- 헤더 회원 메뉴/로그아웃, 체크인 주체를 로그인 회원으로 전환
- 토큰 localStorage 저장(웹/Capacitor 공용)
