Add Cloudflare Domain Detector with datacenter location

Features:
- Scan all domains on server for Cloudflare usage
- Check single domain with detailed analysis
- Detects Cloudflare via: nameservers, IP ranges, HTTP headers
- Shows Cloudflare datacenter location (IATA code from CF-RAY)
- Useful for debugging regional outages and cache issues

Detection Methods:
1. Nameserver check (*.cloudflare.com)
2. IP address check (Cloudflare IP ranges)
3. HTTP header check (CF-RAY, Server: cloudflare)
4. Datacenter location extraction (e.g., ORD, LAX, LHR)

Output shows:
- Domains using Cloudflare [with datacenter code]
- Domains NOT using Cloudflare
- Unknown/uncertain domains

Integrated into Website Diagnostics Menu (option 4)

Example output:
  ✓ pickledperil.com                                [BNA]
