fix(overview): all-clusters overview + cluster-detail now agree on CPU & guest counts

The all-clusters overview and the cluster-detail summary cards disagreed:
- CPU: overview used core-weighted cluster CPU (Σ cpu×cores / Σ cores, from
  datacenter/status); detail used a plain per-node average -> e.g. 6% vs 7.6%.
- Guest counts: overview total = running+stopped from the polled guests summary,
  which drops paused/suspended guests and could transiently render an impossible
  '16 / 14' (total < running); the detail counted all qemu+lxc -> '16 / 30'.

Fixes:
- backend datacenter/status: add explicit per-type guest totals
  (guests.vms.total / guests.containers.total = every guest of that type, any
  status incl. templates) so the overview denominator equals the detail's
  allVms.length and can never be < running. (proxmox + xcpng paths)
- overview (AllClustersOverview + the cluster-group variant): use the explicit
  total when present, fall back to running+stopped for older backends.
- detail summary cards: read the core-weighted CPU from datacenter/status (same
  source as the overview), falling back to the per-node average until it loads.

Verified live vs the Testi cluster: overview 16/30 == detail 16/30, and both CPU
values now derive from a single source. Rebuilt web/index.html.
