feat: GB10 GPU panels + enhanced UniFi widget with health data

- Added GB10 Fabric row: GPU Utilization A/B + Network Throughput
- UniFi widget now shows WAN/WLAN/LAN/Internet health subsystems
- Displays ISP name, bandwidth rates, latency, client counts per subsystem
- Status dots (green/yellow) for each subsystem
