feat(lxc): support reinstall for LXC created from CT template file

Browse Source 
Previously the reinstall endpoint required cached.template_id (clone-from-VM-
template flow), so LXC instances created via the wizard from an OS template
file (e.g. local:vztmpl/debian-13-...tar.zst) returned 'VM has no associated
template; reinstall is not available'.

Now reinstall works in two modes:
  1) clone-from-template (existing): VM/LXC with cached.template_id pointing
     to OSTemplate.vmid
  2) ostemplate-file (new, LXC only): cached.template_name like
     'storage:vztmpl/...tar.zst'. Reinstall stops, deletes, then re-creates
     the container with the same VMID using create_lxc_container, preserving
     network config, storage, rootfs size, swap, features, ssh_keys, etc.
     pulled from the previous container config + VMInstance cache.
