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 Example response: running|31.1%|9.6GiB/20GiB|48.87%|4.7GiB/3.3GiB|25GiB/36GiB
