fix: OS template type matching for LXC/KVM nodes

- Add is_lxc column to ext_proxmox_oses for tracking template type
- OS model now has vmType() helper returning 'lxc' or 'qemu'
- Install uses OS template's type for clone API path (not node type)
- createServer validates OS type matches node type before provisioning
- calculateNode filters nodes by LXC/KVM type based on selected OS
- Reinstall OS list filtered to only show matching template types
- Admin location OS repeater now has LXC Template checkbox
