Fix Proxmox root SSH to allow key-based login for cluster communication 

Proxmox nodes require root SSH key access for inter-node cluster
communication (web UI node switching, live migration, etc.). Set
PermitRootLogin to prohibit-password in group_vars/proxmox.yml so
key-based root login is allowed but password login remains disabled.
