Propagate onMovedToDisplay with ConfigurationRepository

This propagates onMovedToDisplay signal from ConfigurationController to ConfiguratoinRepository, providing a flow that emits the latest display.

For now (and probably forever) the new configuration is neglected, as it's already available from the configuration flow. If it turns out useful in the future, it will be added
