Allow WorkerRun IDs of the user's local process without Ponos task authentication

Most API endpoints now require Ponos task authentication or an instance admin when sending anything with a worker_run_id. This can cause trouble when using WorkerRuns outside of workers, as regular users will not be able to use task authentication.

To let users use those WorkerRuns (currently created with arkindex fake_worker_run), the endpoints that currently require Ponos task auth should also allow WorkerRuns from the Local process of the current user.
