feat: AI 업셀링 CRM - Clawdbot Gateway 기반 맞춤 추천 시스템

키오스크 적립 시 Clawdbot Gateway(Claude Max)를 통해 구매 이력 기반
맞춤 제품 추천을 생성하고, 마이페이지 방문 시 바텀시트 팝업으로 표시.

- ai_recommendations SQLite 테이블 추가 (스키마 + 마이그레이션)
- clawdbot_client.py: Gateway WebSocket 프로토콜 v3 Python 클라이언트
- app.py: 추천 생성 + GET/POST API 엔드포인트
- my_page.html: 바텀시트 UI (슬라이드업 애니메이션, 1.5초 후 자동 표시)
