qm lives at /usr/sbin/qm, which is not in the default PATH for
non-interactive SSH sessions as a non-root user. Add PVE_SUDO (set to
"sudo" when PVE_SSH_USER != root, matching create-proxmox-resource.sh's
own sudo_prefix pattern) and prepend it to all three qm invocations in
the script.

Three-phase online resize: Proxmox qm resize → guest block device
rescan → drbdadm resize + xfs_growfs. No downtime required.
Detects active node via crm_mon, pre-checks DRBD UpToDate/UpToDate,
auto-discovers VMIDs from qm list, and resolves the block device name
from the stable scsi-0QEMU... by-id symlink with a slot-index fallback.
