fix: validation accuracy for global/anycast networks

Browse Source 
- Geolocation: global networks (5+ facility countries) now get pass
  even when MaxMind has no data (was warning)
- Route Server: uses ASN fallback when PeeringDB net_id unavailable
  (was showing "0 IX connections" due to rate limiting)
- IX geocode fallback: CITY_COORDS map + IX_CITY_MAP for 70+ cities

AS49544 (i3D.net/Ubisoft): 100 IX connections correctly detected,
bilateral peering policy recognized, 27-country global presence pass
