fix(abcip): report ALMD transitions with ConditionId = RawPath and a Kind (#641)

Found while verifying item 4 of #641. The host routes a native alarm transition
on an exact ConditionId == RawPath match (DriverHostActor.ForwardNativeAlarm),
but AbCipAlarmProjection emitted "{ref}#active" and no Kind, so every ALMD
raise/clear was dropped as "no alarm condition" — and even if routed, an
Unspecified kind projects no state change. It now reports the subscribed
reference (the RawPath) and Raise/Clear. A host test pins that a decorated id
is dropped.

FOCAS has the same id shape plus a device filter keyed by host address (a
RawPath subscription polls nothing); it needs a mapping decision and is
documented in docs/drivers/FOCAS.md rather than patched here.
