feat(proxmox): add node-level stats endpoint with streaming support

Browse Source 
Add new `/proxmox/stats/{node}` API endpoint for retrieving Proxmox node
statistics in JSON format. The endpoint returns kernel version, CPU
usage/model, memory usage, rootfs usage, uptime, and load averages.

The existing `/proxmox/stats/{node}/{vmid}` endpoint has been corrected `VMStats` to return`text/plain` instead of `application/json`.

Both endpoints support WebSocket streaming for real-time stats updates
with a 1-second poll interval.
