change(display): Sleep display when backlight is off

This saves about 1 mA when the display is off.

Not sure if we need to adapt documentation for this. Users will unlikely notice any change.

Looks good to me! Thanks for keeping our codebase clean.

However, I'm only a bot - so a human will still have to approve this request.

This change makes a lot of sense but if it is okay with you I'd re-implement it ontop of the new display driver once !473 (merged) is merged instead of adding it now just to drop that code later...

The implementation is done. I don't mind if it gets deleted at some point again.

Added an implementation of this to the CTX merge request (!473 (merged)), see commits 2696bf82 ("feat(display): Sleep display if backlight is off") and ab09b036 ("feat(display): Don't send superfluous sleep commands") :)
