Add Glassmorphic Effect to Navbar

[cheshtagarg28]

##Description:
The current navbar has a solid white background, which looks clean but lacks depth and modern feel. Implementing a glassmorphism effect can enhance the overall UI aesthetics by adding a subtle transparency and blur effect, giving the navbar a more elegant, layered look.

##Expected Outcome:
Navbar appears semi-transparent with a frosted-glass effect.
Improved visual hierarchy and premium aesthetic.
Smooth transition when scrolling or hovering.
