Adds the Carrier Management wire surface that drives the FSMs from D1:
S3F17 / S3F18 CarrierAction (host issues ProceedWithCarrier /
CancelCarrier / BindCarrierID / etc.; CommandParameter
list is reused from S2F41).
S3F23 / S3F24 PortGroupChangeReport (equipment notifies host of port
group composition changes).
S3F25 / S3F26 CarrierTransfer (host instructs source -> target port
transfer).
S3F27 / S3F28 CancelCarrier (host cancels an outstanding carrier op).
Two new ack enums in messages_helpers.hpp:
CarrierActionAck — CAACK byte; covers the common error responses
(CarrierIDUnknown, Inaccessible, ActionInProgress).
PortGroupAck — PGACK byte (Accept / Error).
Round-trip tests for all four pairs. Server-side dispatch + the
CarrierStore + LoadPortStore that the FSMs key into land in D3/D4.
