feat: GA4 전환 이벤트 추적 + 전 페이지 스크롤 리빌 애니메이션

- lib/gtag.ts: GA4 이벤트 유틸리티 (trackCTAClick, trackToolDemo, trackDownload, trackOutboundClick)
- ContactModal/ContactForm: 공용 trackEvent로 리팩토링 + generate_lead 이벤트
- 홈/tools/automation/prompt/website: CTA 클릭 이벤트 추적 추가
- 홈/freelance/ai-kit: IntersectionObserver 스크롤 리빌 애니메이션 신규 추가
- automation/prompt: GA4 trackCTAClick 적용
