List user worker runs

Refs https://redmine.teklia.com/issues/4471

A new endpoint ListUserWorkerRuns must be implemented that will list all worker runs tied to local processes (process.creator == request.user and process.mode == ProcessMode.Local).

The endpoint takes no parameters (except for pagination purposes), and is only available to verified users (no ponos auth).

It will use the same serializer as ListWorkerRuns.

The endpoint should be ordered by creation date (most recent first).
