Prevents IllegalArgumentException in Card Browser

[Galal-20]

Purpose / Description

Fixes a common Card Browser crash IllegalArgumentException that happens when the calculated ripple/focus color is the same as the backdrop color.

Fixes

• Fixes: [BUG] Card Browser: MultiColumnViewHolder.setColor: Failed requirement #20888

Approach

I used a defensive fallback logic in place of a necessary requirement that might not work with extreme colors:

The code tries the typical transformation darkening for Light Mode, lightening for Night Mode.
I check to see if the new hue truly differs from the original.
The algorithm automatically applies the inverse.

This ensures the colors will always be different and users always get a visible response pressed state even when using extreme background colors.

How Has This Been Tested?

Tested manually on: Android Emulator (API 33, 34, 37) and Physical device.
Also i have added comprehensive Unit Tests to verify this logic.
