BREAKING CHANGE: switch to iframe-wrapped experience builder app

[Copilot]

Pull request overview

This is a major breaking change that migrates the application from a Dojo-based architecture with Python backend scripts to a modern React + Vite application that wraps an ArcGIS Experience Builder app in an iframe. The PR removes extensive legacy code including Python scripts for data processing, Dojo widgets, tests, and build configurations, replacing it with a minimal React application that embeds the Experience Builder template.

Key Changes:

• Complete migration from Dojo to React with Vite as the build tool
• Removal of Python backend scripts and ArcGIS toolbox integration
• Introduction of Utah Design System components for header/footer
• Simplified architecture using iframe to embed ArcGIS Experience Builder
