edde746 f63a4b039a fix(auth): show the Plex sign-in QR in the app on a car
Signing in opened plex.tv in a browser, and a head unit has none: the user was
left staring at a launcher error with no way to link the account. The QR code and
the linking code are now rendered in the app on a car, so the pairing happens on
a phone while the vehicle shows what to scan.
