fix: prevent footer overlap on tablet viewports

[karthikvemula23]

Description

Summary

Fixes footer layout overlap on tablet-sized and narrow viewport widths.

Changes Made

• Updated the newsletter form width from sm:w-80 to lg:w-80
• Allows the newsletter input to remain responsive on tablet and reduced viewport widths
• Prevents the Updates and Community sections from overlapping with the Navigation section
• Preserves the original desktop appearance by applying the fixed width only on large screens

Result

The footer now maintains proper spacing and alignment across desktop, tablet, and narrow window sizes without content collisions.
