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
Add the go-proxmox library as a Git submodule to enable Proxmox
integration for container/VM management.

* **New Features**
* Multiplexed TLS port: HTTP API and a custom stream protocol can share one port via ALPN.
* Agent-side TCP and DTLS/UDP stream tunneling with health-check support and runtime capability detection.
* Agents now advertise per-agent stream support (TCP/UDP).
* **Documentation**
* Added comprehensive stream protocol documentation.
* **Tests**
* Extended integration and concurrency tests covering multiplexing, TCP/UDP streams, and health checks.
* **Chores**
* Compose/template updated to expose both TCP and UDP ports.
