Move the metadata on each workflow transition from the event subscriber to the entity EntityWorkflow::setStep method

The main update is in the setStep method of EntityWorkflow, where parameters are added to capture the transition details. These include the exact transition, the user who made the transition and the time of transition.

The WorkflowController extracts this information and put it into the transition's context. The MarkingStore transfer it to the EntityWorkflow::setStep method, and all metadata are recorded within the entities themselve.
