feat: add server stats, GPU stats, container CPU/memory display

- Add /api/servers endpoint querying Prometheus for CPU, RAM, disk, uptime, load
- Add /api/gpu endpoint for NVIDIA Jetson GPU utilization, temp, power
- Add ServerStatsWidget with animated bars for Atlas, Wile, RoadRunner
- Add GPUStatsWidget with GPU util, memory, temp color-coding, power draw
- Update ContainerGroup to show CPU bar and memory for running containers
- Fix docker-compose.yml: traefik network external: true
- Fix getTraefikUrl to scan all router labels (not just 'https')
