Add manual SoC changes on main display

I've been using ABRP on my new 2026 Toyota bZ Limited. From what I've been reading online, I can't use the ODB2 port, and using Enode often is incorrect or slow.

Going without isn't the worst thing, but if the displayed SoC is different than the actual on the dashboard, the only way to sync them is to go into Settings, vehicle, then use the -1/+1 buttons. If it is way off Google forces a 5 second wait before continuing.

I think a good idea might be to have that function as part of the main display, perhaps just under the SoC display.
