chore: decommission VM 105 (docker-vpn) — repo cleanup (#20)

VM 105 was already destroyed on Proxmox. This removes stale references:
- Delete server-configs/proxmox/qemu/105.conf
- Comment out docker-vpn entries in example SSH config and server inventory
- Move VM 105 from Stopped/Investigate to Removed in upgrade plan
- Check off decommission task in wave2 migration results

Closes #20
