Update Test Target

Thank you to the internet troll who thought they were "owning" me by pointing out I forgot to update the test target for iOS 17. I appreciate the free testing!

Update all ViewModels to be @State properties.

iOS 17 Update (#2)

iOS 16 Update

* iOS 16 Update

Updated the app to use iOS 16 patterns and features.

* Accessibility updates

* Refactor Color view out of ColorService

Someone on the internet didn't understand abstraction and they were mad that I used Color (the View) inside a service. I refactored it out with this update which really doesn't change much.

* Update README with project architecture description

* Add older OS reference to the README

Cleanup signInOrOut publisher

Add Wizard Coordinator Pattern
