Constrain Proxmox disk sub-rows to a tighter column span

Previous version spanned from Disk all the way to Cluster, which gave
the per-disk bar far more room than it needs and visually fragmented
the table grid. Cap the colspan to Disk plus two right neighbours so
the sub-row sits in a sensible ~400px region, and fix the bar at w-20
instead of letting it stretch. Cts/Cluster columns now stay aligned
with the host row above.
