Registers tenant-engine as a flex-auth protected-system consumer in both
directions its boundary contract requires: tenant-engine's writes need
authorization (FlexAuthWriteAuthorizer in TEN-WP-0003 currently gets
deny/not_applicable for everything until a policy package exists), and
flex-auth's own decisions for other protected systems need tenant
capability roles as context input via a live-lookup adapter.
Scoped closer to FLEX-WP-0006/0007 (ops-warden's small security-lane
integration) than FLEX-WP-0003 (Markitect's CARING-benchmark integration)
-- tenant-engine's resource/action vocabulary is small.
Registered, not implemented.
