main: Add empty battery screen

This disables low battery monitor shutdown (LBM shutdown) on boot and checks if battery is enough.

The logic is as follows:

If battery is not enough:
- If not charging and 15s pass, it will re enable LBM shutdown and power off.
- If charging, it will wait until it is charged above the limit.
 Screen will auto turn off to save power. A press on Power button or a change on charger, will enable it for another 15s.

If battery is enough:
- Enables LBM shutdown and continues with the boot process.
