📱 Fix: Comprehensive Mobile Responsiveness Implementation

Summary

This PR addresses the complete lack of mobile responsiveness in the NEPA frontend application. The implementation transforms the fixed-width desktop-only interface into a fully responsive, mobile-first design that provides optimal user experience across all device sizes.

🚫 Issues Fixed

✅ Fixed Width Layout (400px max) - RESOLVED

  • Before: Application was constrained to 400px maximum width
  • After: Fully fluid layout with responsive breakpoints (xs: 475px, sm: 640px, md: 768px, lg: 1024px, xl: 1280px, 2xl: 1536px)

✅ No Responsive Breakpoints - RESOLVED

  • Before: Single layout for all screen sizes
  • After: Mobile-first responsive design with 6 breakpoints and adaptive layouts

✅ Touch-Unfriendly Interface Elements - RESOLVED

  • Before: Small touch targets, no touch optimization
  • After: 48px minimum touch targets, touch-manipulation class, active states with scale feedback

✅ Poor Mobile Navigation - RESOLVED

  • Before: Desktop-only navigation with horizontal buttons
  • After: Dedicated mobile navigation with hamburger menu, slide-out drawer, and touch-optimized interactions
