App 2.4.3: pairing code visible on the car screen

Browse Source 
The code below the QR code was not visible on the head unit: the dialog
stacked the text, a 240 dp QR code, the code and the status, and its
content could not scroll, so on the wide, low screen the lower part
was cut off. On wide screens the QR code now sits left of the text,
the content scrolls, and the code is also part of the instruction
sentence, so it is readable wherever the text is.
