[JamesVictor-O]

Description

This PR implements comprehensive responsive design improvements across the entire dashboard and demo page to ensure optimal user experience on mobile devices (320px+) and tablets (768px-1024px).

##Key Improvements

1. Layout & Navigation
   ✅ Mobile-first sidebar: Collapsible hamburger menu with smooth transitions
   ✅ Responsive navbar: Stacked layout on mobile, hidden secondary elements on small screens
   ✅ Touch-friendly navigation: All interactive elements meet 44px minimum touch target requirement
   ✅ Proper breakpoints: Mobile (320px-767px), Tablet (768px-1023px), Desktop (1024px+)
2. Dashboard Components
   ✅ Responsive card layouts: Optimized padding, text scaling, and stacking on mobile
   ✅ Chart responsiveness: Dynamic heights (220px-500px), smaller axis ticks, mobile-optimized tooltips
   ✅ Data tables: Horizontal scroll with sticky first column, hidden less important columns on mobile
   ✅ Pagination: 44px touch targets on mobile, improved spacing
3. Performance Optimizations
   ✅ Lazy loading: Dynamic imports for heavy components (AppealAllocation, TransactionTable)
   ✅ Responsive images: Optimized for different screen densities
   ✅ Mobile-optimized charts: Reduced complexity on small screens
