Restructure into one folder per private repo/host, not a flat Docker/ dump

rocky-docker-lxc/, caddy-vm/, monitoring-vm/ (was missing entirely -
Grafana+Loki+Prometheus stack, refreshed and CA mount stripped same as
everything else), and automation/{ansible,automation-vm,iac}/ for the
three repos that live on the automation VM. Hawser is genuinely
deployed on all three of caddy-vm/monitoring-vm/automation-vm so it's
duplicated in each rather than picking one canonical home.

Old Ansible/ and "Infrastrucutre as Code/" content moved under
automation/ansible/old-playbooks and automation/iac/old-content as-is
for now - contents still need refreshing against the current repos and
a per-folder README, that's the next pass.
