[PATCH pve-manager] fix #7794: ui: dc summary: add per-node VM/CT count columns

[Erik Fastermann <e.fastermann@proxmox.com>]

The datacenter summary aggregates VM and CT counts cluster-wide but
gives no per-node breakdown. Add columns to the node list showing the
number of running and total VMs and CTs per node, so the workload
distribution across the cluster is visible at a glance.

The running columns are shown by default, the totals are hidden and can
be enabled per profile. Templates are excluded from the totals, matching
the guest status panel that accounts for them separately.

Combined guest columns (VMs plus CTs) were suggested but left out on
purpose, as one does not gain a lot of information from them and to
avoid column clutter.
