FE: Enhancement: Improve Dashboard Responsiveness and it's Components

Description**

The current dashboard and the demo page have several responsiveness issues that negatively impact user experience across different screen sizes and devices. Users report difficulties navigating and interacting with dashboard components on mobile devices and tablets.

## **Current Issues**

- **Mobile Layout Problems:**
- Components overflow on screens < 768px
- Navigation menu not optimized for touch interfaces
- Charts and graphs become unreadable on small screens

- **Tablet Experience:**
- Awkward spacing and sizing on medium screens (768px - 1024px)
- Touch targets too small for comfortable interaction

## **Proposed Solution**

Implement comprehensive responsive design improvements across all dashboard components and demo page:

### **1. Layout Improvements**
- [ ] Implement CSS Grid/Flexbox for better responsive layouts
- [ ] Add proper breakpoints for mobile (320px-767px), tablet (768px-1023px), desktop (1024px+)
- [ ] Create collapsible sidebar navigation for mobile
- [ ] Optimize card layouts with proper stacking on smaller screens

### **2. Component Enhancements**
- [ ] **Charts & Visualizations:**
- Implement responsive chart libraries (Chart.js responsive config)
- Add horizontal scrolling for data tables on mobile
- Create mobile-optimized chart legends and tooltips

- [ ] **Navigation:**
- Convert desktop navigation to mobile hamburger menu
- Ensure touch targets are minimum 44px × 44px
- Add swipe gestures for mobile navigation

- [ ] **Forms & Inputs:**
- Optimize form layouts for mobile input
- Implement proper keyboard types for mobile inputs
- Add better validation feedback for touch interfaces

- [ ] **Data Tables:**
- Implement responsive table patterns (stack/collapse columns)
- Add horizontal scroll with sticky first column
- Create mobile-friendly pagination controls

### **3. Performance Optimizations**
- [ ] Implement lazy loading for dashboard widgets
- [ ] Optimize images with responsive image techniques
- [ ] Add loading skeletons for better perceived performance
- [ ] Minimize CSS/JS bundle sizes for mobile

## **Technical Requirements**

### **Breakpoints**
```css
/* Mobile First Approach */
@media (min-width: 320px) { /* Mobile */ }
@media (min-width: 768px) { /* Tablet */ }
@media (min-width: 1024px) { /* Desktop */ }
@media (min-width: 1440px) { /* Large Desktop */ }
```
## **Acceptance Criteria**

### **Visual Design**
- [ ] Dashboard is fully functional on screens as small as 320px wide
- [ ] All interactive elements have appropriate touch targets (44px minimum)
- [ ] Typography scales appropriately across all screen sizes
- [ ] No horizontal scrolling unless intentionally designed (e.g., data tables)

### **Functionality**
- [ ] All dashboard features accessible on mobile devices
- [ ] Navigation works smoothly with touch gestures
- [ ] Charts and graphs remain readable and interactive on small screens
- [ ] Forms are easy to complete on mobile keyboards

### **Testing Requirements**
- [ ] Test on real devices (iPhone, Android, iPad)
- [ ] Verify accessibility with screen readers
- [ ] Performance testing on slow networks
- [ ] Cross-browser testing (Chrome, Safari, Firefox mobile)
