Introduce an endpoint

Hello, I believe it would be a valuable improvement to provide an endpoint that exposes the number of blocked ads per client. Since the /history/database/clients endpoint already exists, it would make sense to extend it by including, as a first step, the number of blocked ads per client. I am currently working on a personal dashboard, and having access to these statistics would be very helpful. I also believe this could benefit the entire community.
