A control-group VM that applies base with INPUT-only default-deny (forward
policy accept; admin-addr SSH allow). verify.yml is now profile-aware via an
integration_profile marker — the askari Docker/DNAT block is gated, and a ubongo
block asserts input drop + forward accept + the admin-addr rule. Enables
`make test-integration HOST=ubongo`. Mesh-hardening 2/3 (ADR-025).
