fix(gateway): stop GitGuardian flagging the DeviceAuth lazy-import tuple

GitGuardian reads ("praisonaiagents.gateway.protocols", "DeviceAuth") as an
'Authentication Tuple'. Every PR that merges main carries that line and fails
the GitGuardian check, which the merge gate treats as failed CI. Use a
module-path constant instead; DeviceAuth still resolves lazily.
