  do toggle this too quickly.

Keydisabler: fix button light restore logic

Do not assign default button brightness if backup key is not found.
Instead do nothing. This will prevent brightness being reset to default
on boot when navbar is disabled.

If backup key is not found when actually toggling navbar then we've got
bigger problems.

Settings: Change 'Model Number' to 'Model Name'

Most devices have the Model Number set to something like 'One' rather
than 'PN072', therefore they are using the Model Name not the Model
Number. Therefore, either every device should update to properly refer
to the Model Number, or we should update Settings to correctly state
that it is the Model Name.
