🪲[Bug]: [UI Bug] Support Us dropdown text misaligned and unreadable in mobile navigation

**Describe the bug**
When opening the navigation menu on smaller screens (mobile view), the Support Us → Become a Volunteer dropdown is misaligned. The text is partly cut off, overlapping with the background, and has poor visibility compared to other menu items.

**To Reproduce**
Steps to reproduce the behavior:
1.Open the site on mobile or shrink the browser window.
2.Click the hamburger menu (top-right).
3.Expand the Support Us dropdown.

**Expected behavior**
->The "Become a Volunteer" option is not properly aligned.
-> Text overlaps and is hard to read due to background contrast.

**Screenshots**

**Desktop**
OS: Ubuntu Linux 24.04
Browser: Firefox (latest version)

**Additional context**
The dropdown styling for "Support Us" seems inconsistent with the rest of the nav menu. Likely a CSS issue with positioning or background contrast.
