Enatega Customer Application: Extra White Border Appearing Around Banners

Describe the bug

To Reproduce
Steps to reproduce the behavior:

Open the app and navigate to the section where banners are displayed (e.g., homepage).
Observe the banners on different screens and layouts.
Notice the extra white border around the banner images.
Expected behavior
Banners should display without any extra border unless intentionally designed.
