Refactor code by renaming and moving classes

Renamed 'VehiculeActivity', 'VehiculeUIHandler' to 'VehicleActivity', 'VehicleUIHandler' and moved them to their separate files. A debouncer was added to InputsTab in the WorkflowDefinitionEditor to limit the rate of firing refresh requests. Optimized codes by reducing unnecessary lines and improved consistency in the 'Program.cs' file.
