fix: use node-specific Proxmox config paths for VM vs LXC detection

- isVM(): check /etc/pve/nodes/<server.name>/qemu-server and lxc first, fallback to /etc/pve/qemu-server and lxc for single-node
- checkConfigAndExtractInfo, config-existence checks, getContainerHostname, addClonedContainerToDatabase: use node-specific paths
- syncLXCConfig/updateLXCConfig: use node-specific LXC config path
- server.js clone flow: use node-specific config path

Fixes #464
