fix(longhorn): retire the failed 2TB PERC disk on talos-cp-2

The disk behind /var/lib/longhorn-disk4 (sde1, 2TB PERC H710P virtual disk)
failed: 54 million SCSI I/O errors and climbing at ~7,000/minute, against 3 on
every other device on the node. Its XFS filesystem hung, so five Longhorn
replica processes and the longhorn-manager blocked in uninterruptible D state
in openat and unlinkat. D-state processes cannot be killed, so they held the
node's three replica rebuild slots permanently: no new replica could start on
talos-cp-2 and every new volume there failed to attach with DeadlineExceeded.
That is what stopped the azhi database from coming up.

Removed from all three declarations so it cannot come back:
- terraform.tfvars.local.bak, longhorn_disks for talos-cp-2
- the Longhorn add-disks Job, which would otherwise re-register it
- the Job's disk-count guard, 5 -> 4, or it would fire on every run once the
  disk is gone

The running cluster already has the disk fenced
(allowScheduling=false, evictionRequested=true); the replicas are evicted and
the device retired at the controller after that.
