Add "light day" in chart range selectors

It would be nice to have “light day” (from sunrise to sunset) in chart range selectors. Which is based on current location.

That would be useful for displaying solar power production.

Note that a server & numerous clients may be located in different TZs.
And a location of a “home” is defined → the “Sun” integration gives “sunrise” & “sundown” values for this location. Means - “light day” can be different for different clients if a “client time” is selected in settings.
