fix(vm): fix LVM/LVM-thin storage and error reporting for all VM scripts

- Add catch-all (*) case to storage type detection in all VM scripts
  that were missing it (debian-vm, debian-13-vm, ubuntu2204/2404/2504,
  nextcloud-vm, owncloud-vm, opnsense-vm, pimox-haos-vm)
- Add catch-all to mikrotik-routeros (had zfspool but not lvm/lvmthin)
- Fix error_handler in ALL 14 VM scripts to send numeric exit_code
  to post_update_to_api instead of bash command text, which caused
  'Unknown error' in telemetry because the API expects a number
