feat: add CDN cache hit rate for accurate bandwidth cost estimation

- Add cdn_enabled and cdn_cache_hit_rate API parameters
- Use case별 기본 캐시 히트율 자동 적용 (video: 92%, blog: 90%, etc.)
- 원본 서버 트래픽(origin_monthly_tb)과 절감 비용(cdn_savings_cost) 계산
- 응답에 CDN breakdown 필드 추가 (bandwidth_estimate, bandwidth_info)
- 캐시 키에 CDN 옵션 포함하여 정확한 캐시 분리
- 4개 CDN 관련 테스트 추가 (총 59 tests)
- CLAUDE.md 문서 업데이트

Cost impact example (10K video streaming):
- Without CDN: $18,370 → With CDN 92%: $1,464 (92% savings)

refactor: major architecture improvements and security hardening

## Security Fixes
- Fix XSS vulnerability in report.ts with escapeHtml()
- Add cache data integrity validation
- Add region_preference input validation (max 10 items, 50 chars each)
- Replace `any` types with `unknown` + type guards

## Architecture Refactoring
- Split utils.ts (801 lines) into 6 modules: http, validation, bandwidth, cache, ai, exchange-rate
- Extract AI logic to src/services/ai-service.ts (recommend.ts 49% reduction)
- Add Repository pattern: src/repositories/AnvilServerRepository.ts
- Reduce code duplication in DB queries

## New Features
- AI fallback: rule-based recommendations when OpenAI unavailable
- Vitest testing: 55 tests (utils.test.ts, bandwidth.test.ts)
- Duplicate server prevention in AI recommendations

## Files Added
- src/utils/{index,http,validation,bandwidth,cache,ai,exchange-rate}.ts
- src/services/ai-service.ts
- src/repositories/AnvilServerRepository.ts
- src/__tests__/{utils,bandwidth}.test.ts
- vitest.config.ts
