Fix all issues and deploy iPhone app to Netlify with complete PWA features

[Copilot]

This PR addresses the "fixx all and deploy netlify" issue by implementing a complete iPhone-optimized Progressive Web App with all necessary static files, PWA features, and Netlify deployment configuration.

Problem Fixed

The repository had several critical issues preventing successful deployment:

• Missing src/public/ directory and all static files (HTML, CSS, JS, PWA assets)
• Test failures (3 out of 7 tests failing due to missing files)
• Incomplete PWA implementation
• No iPhone-specific optimizations

Solution Implemented

📱 Complete iPhone-Optimized Web Application

Created a full-featured iPhone app with:

Core Static Files:

• src/public/index.html - iPhone-optimized HTML with proper viewport settings, PWA meta tags, and responsive design
• src/public/manifest.json - Complete PWA manifest with iPhone-specific icons and configurations
• src/public/sw.js - Service Worker with intelligent caching, offline support, and background sync

Styling & Interactivity:

• src/public/css/styles.css - Modern responsive CSS with glass morphism effects and mobile-first design
• src/public/css/iphone.css - iPhone-specific optimizations including safe area support, dark mode, and touch interactions
• src/public/js/app.js - Interactive JavaScript with PWA installation, health monitoring, and performance tracking

PWA Assets:

• Complete icon set for different iPhone models and PWA requirements
• Apple touch icons for home screen installation
• Favicon set for browser compatibility
• Screenshot placeholders for app store listings

🚀 Netlify Deployment Ready

Configuration:
