docs: replace hardcoded infra details in README with pointers to index pages

Problem: README listed specific IPs, container IDs, and per-host counts (e.g.
"hubris (15 active): 102 nfs-export, 103 paperless..."). This duplicates
inventory.yaml and the wiki index pages, and goes stale every time a node
moves, gets added, or is destroyed — exactly what happened during the strong
migration.

Fix: Replaced the Proxmox Hosts / VMs / LXC Containers / Cross-Cutting
Infrastructure subsections with plain pointers to their authoritative index
pages (knowledge/wiki/{hosts,vms,containers,infrastructure}/index.md).
Also dropped the "Last refreshed against live state" date line — another
claim that goes stale without a mechanism to keep it honest.

README's job is navigation, not a live topology snapshot.
