Display switch in Home Assistant (display on/off)

Hi,

first of all, thanks for Tessera, it's a great project!

I'm using a CYD (ESP32-2432S028) and would love to have a switch entity in Home Assistant that fully turns the display / backlight off and on again, independent of standby and night hours.

The reason: I'd like to turn the display off via automation (e.g. when nobody is home) to extend the backlight's lifespan and save power. A touch on the screen or an automation could turn it back on when needed.

Would this be feasible? I'm happy to test it if you have a dev build.

Best regards Collin
