Closes the slot-map verification gap I called out:
S3F19 / F20 host -> equip: verify expected slot map against what
the equipment has scanned. Equipment compares element-
wise; on match drives CSMS NotRead -> Read and replies
SVACK=Accept; on mismatch drives CSMS -> Mismatched and
replies SVACK=Mismatch.
S3F21 / F22 equip -> host: equipment-initiated slot map report
(typically pushed after CARRIERID is confirmed).
New SVACK enum: SlotMapVerifyAck { Accept, Mismatch, CarrierUnknown,
Error }. Server dispatch on S3F19 wires the actual CSMS transition
through the CarrierStore from D3.
Two round-trip tests cover both pairs; the FSM-driving behaviour is
exercised through the in-process tests because secs_server.cpp is
the dispatch entry point (no separate integration test needed beyond
the wire round-trip).
