Adds the ADR-025 integration-test profile that proves the askari
mesh-hardening REDESIGN (INPUT-only default-deny, forward ACCEPT for Docker)
is reboot-safe on a throwaway KVM VM before the live cut-over.
Profile applies base (firewall + sshd) and offsite (docker_host +
reverse_proxy). Post-reboot verify checks: input policy drop, forward
policy accept, admin-addr break-glass SSH (192.168.150.1), Docker up,
and a published port answered from the controller. GREEN on 2026-06-19.
