fix: null gateway latency; skip aiwanbal generic modem_type for carrier detection

Browse Source 
- Gateway ping latency is LAN RTT (<1ms), not WAN latency; set to null so
  dashboards don't show misleading sub-ms values for Eyeride-NAT'd interfaces
- aiwanbal reports modem_type=generic for wired ISP ports; treat same as none
  so carrier detection falls through to gateway IP pattern matching (AT&T etc.)
