fix(core): use buttons__cancel in Delizia menu to cancel PIN setup

What changed, and why it matters

This is a tiny user-interface wording fix in the Trezor hardware wallet firmware. It changes the label on one menu button from a long translated phrase ('cancel setup') to a shorter generic word ('Cancel') so that translations fit on screen. There is no direct evidence this is a security vulnerability; it is a UI polish fix that may slightly reduce user confusion when setting up a PIN.
