the requirement to implement a notification template preview feature as outlined in the project issue. + +## 📋 Summary + +This PR implements a comprehensive notification template preview system that allows users to preview notification templates before sending them, with support for dynamic variable substitution, metadata display, and responsive design across all screen sizes. + +## ✨ Features Implemented + +### Core Requirements ✅ + +1. **Preview Modal Component** + - Fully accessible modal with ARIA attributes + - Keyboard navigation (Tab, ESC, Enter) + - Focus management and restoration + - Backdrop and close button interaction + - Smooth animations and transitions + +2. **Dynamic Template Variable Support** + - Automatic variable extraction from templates (`{{variableName}}` format) + - Real-time variable editing with live preview updates + - Smart default values based on variable names + - Validation for required variables with visual feedback + - Reset functionality to restore sample values + +3. **Notification Type Support** + - **Discord**: Rich embed previews with colors, fields, and timestamps + - **Email**: Complete email preview with headers, subject, HTML/plain text body + - **SMS**: Mobile device mockup with character count and multi-segment warnings + - **Webhook**: HTTP request preview with method, URL, headers, and JSON payload + +4. **Metadata Display** + - Template ID, name, and type + - Creation and update timestamps + - Variable count and comprehensive list + - Custom metadata fields + - Color-coded notification type badges + +5. **Responsive Design** + - Mobile-first approach + - Breakpoints at 768px (tablet) and 480px (mobile) + - Adaptive grid layouts + - Touch-friendly interactions + - Optimized for all screen sizes + +### Additional Features 🚀 + +- **Raw JSON Payload View**: Debug view showing the exact JSON that will be sent +- **Sample Variable Values**: Pre-populated with intelligent defaults +- **Variable Substitution Engine**: Supports nested objects and arrays +- **Validation Engine**: Ensures all required variables are filled +- **Type-Safe Implementation**: Full TypeScript support with proper type definitions +- **Navigation
