Create Modern React Dashboard with shadcn/ui Components

[Copilot]

This PR completely replaces the HTML-based technical indicators demo with a modern React application built using shadcn/ui components. The new implementation creates a professional dashboard interface that matches contemporary web application standards.

Key Changes

Technology Stack Upgrade:

• Replaced static HTML/CSS with React 18 + TypeScript
• Integrated shadcn/ui component library with Tailwind CSS
• Set up Vite for modern build tooling and static site generation

Dashboard Features:

• Sidebar Navigation: Clean navigation with sections for Dashboard, Lifecycle, Analytics, Projects, and Team
• Metric Cards: Display key performance indicators (Total Revenue, New Customers, Active Accounts, Growth Rate) with trend indicators
• Chart Visualization Area: Placeholder for future technical indicator charts and data visualization
• Interactive Data Table: Document management interface with filtering and status indicators
• Responsive Design: Mobile-friendly layout that adapts to different screen sizes

Implementation Details:

• Built using modern React patterns with TypeScript for type safety
• Leverages shadcn/ui components (Card, Table, Button) for consistent design system
• Uses Lucide React icons for professional iconography
• Configured for static deployment at docs/demo/dist/

The new dashboard provides a much more professional and extensible foundation for showcasing technical indicators, replacing the previous basic HTML structure with a modern React application that can easily be enhanced with interactive charts and real trading data visualization.
