fix: improve visibility of impact statistics

[mohammad-faisal862]

📝 Description

This PR improves the visibility of statistics in the "Our Impact" section of the application.

The metric values (such as 50K+, 1M+, 200+, 95%) were previously difficult to read because they were styled using a gradient text effect that blended into the background in certain themes.

This update replaces the gradient styling with solid, theme-friendly colors to ensure better readability across both light and dark modes.
