fix(deploy): wire native-alarm-source capability validation into flattening pipeline (#22)

FlatteningPipeline loaded data connections but never passed the alarm-capable
connection set to SemanticValidator, so the native-alarm-source capability check
(built but inert) never ran — a source bound to a non-alarm-capable connection
deployed silently. Compute the capable set (IAlarmSubscribableConnection: OPC UA
+ MxGateway) and thread it through ValidationService to SemanticValidator.
