🚀 feat: Implement Chat Application UI Components

📋 Description

This PR introduces a comprehensive chat application interface built with React, TypeScript, and Tailwind CSS. The implementation provides a modern, responsive chat UI with a well-structured component architecture that follows industry best practices.

🎯 Problem Statement

The application lacked a chat interface to facilitate real-time communication between users. There was a need for:

• A responsive chat UI that works across different screen sizes
• Proper component architecture for maintainability and reusability
• TypeScript integration for type safety and better developer experience
• Modern design following current UI/UX trends

✨ What's Changed

🏗️ Component Architecture

• MainLayout: Root container managing the entire chat layout
• ChatSidebar: Left panel containing search functionality and profile list
• ChatWindow: Main chat area with header, message display, and input controls
• Reusable Components: SearchBar, ProfileItem, ProfileList, ChatHeader, MessageArea, MessageInput

🔧 Technical Implementation

• TypeScript: Full type safety with proper interfaces and type definitions
• React Hooks: State management using useState for profile selection
• Tailwind CSS: Responsive design with consistent styling and smooth animations
• Lucide Icons: Professional iconography for enhanced UX

🎨 UI/UX Features

• Dark Theme: Modern dark color scheme with blue accents
• Interactive Elements: Hover states, active selection, and smooth transitions
• Status Indicators: Online/offline status with visual indicators
• Notification System: Unread message counters
• Responsive Design: Optimized for desktop and mobile devices
