Future Proxmox Split

Keldagrim (10.0.0.110) is the current Proxmox host and runs Varrock, Lumbridge,
and Ardougne. When a second system is available, separate GPU and services workloads
across two Proxmox hosts.

TODO

• Install and configure the new Proxmox host as Yanille.
• Decide and document the final IP assignments and ordering for Keldagrim, Yanille, and their VMs before migrating workloads.
• Back up Ardougne application data and the affected Proxmox VMs.
• Move the services and monitoring workload from the current host to Yanille, then verify Caddy, Homepage, Uptime Kuma, and service recovery.
• Update AdGuard DNS rewrites, Inventory and Services, Routing and Access, Proxmox, and any affected Ansible inventory or service configuration after the migration.
