📄 Description

This PR allows the server to send callback events to the client.

Limited to the invoke and batch end points for the time being.

This PR does NOT include the client code to use the events (will be included
in a separate PR to keep things simple).

Also updating the serializer to use an interface -- placeholder for future code
to accommodate user adding their own custom pydantic objects.
