WorkerRun ID permission checks on CreateClassification, CreateElement and CreateTranscription

Closes #1494 (closed), implements part of #1496 (closed)

This updates the three endpoints that already had some checks in place on the worker_run_id to allow local processes to everyone and restrict non-local to Ponos tasks on the same process. We can use the WorkerRunIDField to enforce those requirements more easily on other endpoints with no current checks later on.
