Improved color picker with full HEX code input and no clipping

Choosing colors just got easier and more reliable. We've fixed an issue where the color picker dropdown would sometimes get cut off or hidden when inside scrollable or constrained areas. Now it stays fully visible, no matter where you open it.

**Direct HEX code input for precise colors**
Alongside the standard color swatches, you can now type in HEX color codes directly. The input automatically adds the # symbol if you forget, checks your input as you type, and updates the color preview instantly. This gives you more control if you prefer working with exact color values.

These changes make customizing backgrounds and text colors more intuitive and frustration-free, whether you pick manually or enter your exact shade.
