Adapt USER-WP-0021 and USER-WP-0023 to published policy-nexus contracts

IAM Profile v0.3 and Tenancy Posture v0.1 are now live on
policy.coulomb.social. Close the portal expansion workplan against those
documents, keep the flex-auth live A2 probe waiting, and forward optional
tenant_roles to flex-auth without authorizing from them locally.
