feat: Update project dependencies and configuration

This commit updates the project's dependencies, including React, Recharts, and Lucide React, to their latest stable versions. It also introduces a `server.js` file to handle static file serving with Express for better production deployment. Additionally, TypeScript and Vite configurations have been refined for improved build performance and type safety.
