feat: add LXC container support to Proxmox extension

- Add is_lxc boolean column to ext_proxmox_nodes (default false, existing nodes unaffected)
- Add LXC checkbox to admin node creation form (disabled on edit)
- Dynamic API path selection via Node::vmType() (returns 'lxc' or 'qemu')
- LXC deployment: syncLxcSettings() for cores, memory, swap, hostname, rootfs, net config
- LXC network uses name=eth0 format with applyLxcPoolSettings() for VLAN/firewall/MTU
- All lifecycle operations LXC-aware: install, suspend, unsuspend, terminate, upgrade, reinstall
- VNC/xterm console uses correct type (lxc vs kvm)
- All 20+ Livewire components use vmType() for Proxmox API paths
- LXC user interface shows basic-only view (no advanced toggle, no KVM-specific tabs)
- Basic tabs for LXC: Overview, Network Configuration, Backups, Console
