feat: 프론트엔드 모노레포 이관 + signal-batch 연동 + Tailwind/i18n/테마 전환

- frontend/ 폴더로 프론트엔드 전체 이관
- signal-batch API 연동 (한국 선박 위치 데이터)
- Tailwind CSS 4 + CSS 변수 테마 토큰 (dark/light)
- i18next 다국어 (ko/en) 인프라 + 28개 컴포넌트 적용
- 레이어 패널 트리 구조 재설계 (카테고리별 온/오프, 범례)
- Google OAuth 로그인 화면 + DEV LOGIN 우회
- 외부 API CORS 프록시 전환 (Airplanes.live, OpenSky, CelesTrak)
- ShipLayer 이미지 탭 전환 (signal-batch / MarineTraffic)
