OneShotShelve / TimedShelve / Unshelve now reach the ScriptedAlarmEngine.
Scripted-alarm condition nodes get a ShelvedStateMachine subtree created
before alarm.Create so the stack wires each shelve method's dispatch
handler; AlarmConditionState.OnShelve / OnTimedUnshelve route to the
engine and mirror the result onto the OPC UA node via SetShelvingState.
The three per-instance shelve method NodeIds are indexed so the Call gate
resolves them to OpcUaOperation.AlarmShelve instead of falling through to
generic Call. Engine dispatch is split into the node-free InvokeEngineShelve
so the routing decision is unit-testable.
Adds 9 unit tests; updates phase-7-status.md Gap 1 (only AddComment remains
unwired) and the #24 entry in looseends.md.
