Updates VMID parameter and field types from int to uint64 throughout the Proxmox provider implementation,
including API request structures, provider structs, client methods, and LXC-related functions.
Also updates string conversion calls from strconv.Itoa to strconv.FormatUint.
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.
Implement a new API endpoint to retrieve real-time statistics for Proxmox
LXC containers, similar to `docker stats` functionality.
Changes:
- Add `GET /api/v1/proxmox/stats/:node/:vmid` endpoint with HTTP and WebSocket support
- Implement resource polling loop to cache VM metadata every 3 seconds
- Create `LXCStats()` method with streaming (websocket) and single-shot modes
- Format output as: STATUS|CPU%|MEM USAGE/LIMIT|MEM%|NET I/O|BLOCK I/O
- Add `GetResource()` method for efficient VM resource lookup by kind and ID
- Fix task creation bug using correct client reference
