Pull Request Overview

This PR fixes an IIS deployment issue by making the base URL configurable based on the build mode. The main change ensures that the application uses /react-demos/ as the base path in production while using / for local development.

Key Changes:

• Made the Vite configuration mode-aware to set different base URLs for production vs. development
• Updated the router to use the environment-based base URL instead of a hardcoded value
• Added explicit type definitions for Vite client and Node to TypeScript configuration
