Refactor dark mode color blending to extension method

Moved dark mode color blending logic to a Color extension (toDark) in the design system. Updated usages in ui_utils.dart and related tests to use the new extension. Removed the old getDarkModeColor function for cleaner and more idiomatic code organization.
