Refactor RecAction commands to new namespace

Moved CreateRecActionCommand and DeleteRecActionsCommand (and their handlers) from ReCActionViews.Commands to ReCActions.Commands. Updated all references in controller and mapping profile. Removed old files to improve code organization. No changes to command logic.
