Energy saves a flag via `processingModuleData` identifying the configuration as a target for the module - rework this in the graph/node framework

Energy saves a flag via processingModuleData identifying the configuration as a target for the module (i.e. dissolve().processingModuleData().realise<bool>("IsEnergyModuleTarget", targetConfiguration_->niceName(), GenericItem::ProtectedFlag) = true; ) - how do we rework this in the graph/node framework?
