Refactor WorkerController to manage job state via API

Removed endpoints for starting/stopping/restarting the Worker service. Controller now uses JobStateManager to get and set the state of specific jobs (e.g., FinalizeDocumentJob) through new GET and POST endpoints. Focus shifts from service lifecycle control to job state management.
