feat: 이베이 부품 AI 리스팅 툴 — 실제 크롤링·AI·가격 모듈 구현

Browse Source 
[핵심 모듈 (lib/ebay-tools/)]
- types.ts: 검색 요청/결과/크롤링/가격 공통 타입 정의
- crawler.ts: RockAuto HTTP 크롤러 + eBay 검색 (cheerio, UA 로테이션)
- ai-analyzer.ts: Claude API Tool Use로 크롤링 결과 구조화 (lazy 클라이언트, 런타임 검증)
- pricing.ts: 환율 API 연동 + HS Code 관세 + VAT + 소액면세 계산

[검색 API]
- Mock 데이터 → 실제 크롤링+AI+가격 파이프라인으로 교체
- AI 실패 시 fallback 결과 생성
- 입력값 50자 제한 + 허용 문자 검증

[프론트엔드]
- 중복 타입 제거 → lib/ebay-tools/types import
- 가격 탭에 VAT, 총 수입비용, 면세 여부, 면책 문구 추가

[DB]
- 004_ebay_search_history.sql: 검색 이력 테이블 + RLS (anon 전체 권한 제거)

[Evaluator 반영]
- anon RLS 보안 취약점 수정
- AI 응답 런타임 필드 검증 추가
- Anthropic 클라이언트 lazy 초기화
