Feat built onboarding steps into one

[davedumto]

Description

This PR refactors the onboarding flow from a multi-page routing approach to a single-page design with state management. The new implementation eliminates page reloads between steps while maintaining the same user experience and visual design. Additionally, all static/hardcoded data has been replaced with dynamic values that flow through the entire onboarding process.

Additional Notes

This implementation provides several benefits:

1. Improved user experience with smoother transitions between steps
2. Enhanced data persistence - all form data is maintained in a central state
3. Added animated progress indicators that provide visual feedback during step transitions
4. Replaced hardcoded UI elements with dynamic data from form inputs
5. Added loading states for better feedback during asynchronous operations

The refactoring was done with an emphasis on maintaining the existing visual design while improving the underlying architecture. Placeholder code has been added for icon imports that will be replaced with actual assets.
