Viktor Barzin c24b4a21d8 docs(architecture): fix stale 5-node claim -> 7 nodes (k8s-node1..6) [ci skip] 
Cluster grew to 7 nodes (k8s-master + node1..6; node5/6 added ~10d ago)
but several docs still said "5 nodes". Corrected with live specs:

- overview.md: 7-node enumeration; node1 is 16c/48GB (doc wrongly said
  32GB), node2-6 are 8c/32GB general workers
- compute.md: "5-node" -> "7-node" cluster description
- dns.md: NodeLocal DNSCache DaemonSet "5 nodes" -> "7 nodes"
- mailserver.md: HAProxy backend diagram "node1..4" -> "node1..6"

Illustrative "0/5 nodes available" scheduler-error examples left as-is.
