Pull Request Overview

This PR refactors the selected color state management to use Jotai library instead of local React state. The refactoring introduces centralized color state management through atoms and custom hooks, following the same pattern as a previous refactoring effort.

• Migrated selectedColor and selectedColorBackground from local React state to Jotai atoms
• Created a custom hook useSelectedColor to abstract color state operations
• Removed prop drilling by eliminating color-related props from component interfaces

This code attempts to access colorPalette[0] after filtering out the selected color, but if the selected color was the only color in the palette, this would cause an error when trying to access an undefined element. Consider checking if the filtered array has elements before accessing the first element.
