Fixes color shading for formation annotation.

Browse Source 
Addresses an issue where color shading for formation annotations was not working as expected due to a null color legend in `RimWellLogTrack`.

Implements a fallback mechanism to use the default legend colors when the color shading legend is not available, ensuring proper visualization of formation annotations.
