Extract maestroTransport() (Maestro's identity cert + instance CA) and expose PeerTransport()/Scheme()/InsecureInternal() so every service peer edge uses the same client. RunAction now targets https://{ip}:{port}/action/{name} presenting Maestro's cert (services require a CA-issued client cert, so only Maestro can drive actions — T4) and FetchManifestWithRetry fetches /_manifest the same way. INSECURE_INTERNAL=1 keeps the dev fleet plaintext (debug compose updated to set it).
