EventFilter.AddSelectClause(type, "ActiveState/Id") does not split the string;
it selects a single QualifiedName named "ActiveState/Id", which no event carries.
AckedState/Id, ActiveState/Id and EnabledState/Id therefore always arrived null
and Client.CLI 'alarms' (and Client.UI) reported every alarm inactive and
unacknowledged while a direct Read said Active. Pre-existing since a2883b82;
server-side event delivery was correct (proven with two-element select clauses,
incl. after #629). Select them with explicit two-element browse paths.
Over-the-wire test drives OpcUaClientService.SubscribeAlarmsAsync against the
in-process server (native + scripted); ServerEventRig now also selects
ActiveState/Id, Severity and Retain.
