fix(dialogs): handle cancel flows without false action failures

- treat FilePicker close events as user cancels and return safely from move/restore flows

- guard dialog .show() promises so cancel/close does not surface fake error toasts

- apply the same safe-cancel pattern to Move, Export, and Swarm Reference dialogs
