fix(quality-control): Send the new receiver constraints on state changes.
The client now listens for changes to lastN, selectedEndpoints and maxReceiverVideoQuality in redux to trigger sending bridge message in the new format. This fixes an issue where the stage view <-> tile view changes prompt two receiver constraints messages to be sent, first with the maxHeight update and then with the selected endpoints update.
