a11y(demo): make the device-code sign-in screen-reader friendly

- Move focus to the code instructions when they appear, so SR users land on the code instead of being left on the button with no feedback. - Add a "Copy code" button (with a polite live-region confirmation) so users don't have to transcribe the code by ear. - Give the code an aria-label that spells it out ("W X Y Z dash 1 2 3 4") so it is announced clearly character by character. - Present the steps as an ordered list; announce the waiting state and the signed-in result via live regions.
