Two new assertions: license table has tenant_id/license_id/token/ installed_at/installed_by/expires_at/last_validated_at columns with expected types + NOT NULL constraints, PK on tenant_id; environments has execution_retention_days/log_retention_days/metric_retention_days all integer NOT NULL DEFAULT 1. Note: V5 migration does not include an installed_via column; the plan's spec was aspirational. Test asserts what the migration actually creates (and what PostgresLicenseRepository reads/writes).
