Added Percentage Display for Adjustment Sliders

Description

This PR improves the UX of the Adjustments section by displaying percentage values next to the Brightness, Contrast, and Saturation sliders.

Users can now clearly see the exact adjustment being applied (e.g., +30%, -50%) instead of relying only on slider position.

Additionally, saturation percentage values are now capped at 100% for better consistency and usability (previously values could display up to 200%).
