feat: website scanner with SOLL/IST service comparison + corrections

- website_scanner.py: multi-page crawl, 20+ service patterns (tracking,
  CDN, chatbots, payment, fonts, captcha, video), AI text detection
- dse_service_extractor.py: LLM extracts services from privacy policy text
- agent_scan_routes.py: POST /agent/scan — combines scan + DSE comparison,
  generates findings (undocumented, outdated, third-country transfer),
  auto-corrections via Qwen in pre-launch mode
