[Enhancement] Scale bar text hard to read when map in satellite mode

I know we can change the text color manually but it would be more convenient if the color can be changed automatically according to map style...

No source file, test, or entry point is named in the issue. Start by locating the scale bar text-color handling and the map-style information used by the Android plugin; done means the text color changes automatically for satellite styling while preserving manual color control.
