Feature/search 2

The iOS implementation of Abhiek187/ez-recipes-web#8 & Abhiek187/ez-recipes-web#205.

This is a continuation of #37 and includes the following changes:

• A similar pattern to the HomeView where we show a ProgressView and then navigate to the search results (with the same loading messages)
  • This involved juggling some stuff between SearchView, FilterForm, and SubmitButton, but I was able to find a way
• Responsive recipe cards on the results screen
• Transitioning from the search results to the RecipeView, while passing data between ViewModels
  • In doing so, I removed the need for a global @EnvironmentObject
• Fixed how async images load so they stay within the specified dimensions
• A secondary view for iPads
• Unit tests for the SearchViewModel
• SearchView UI tests

Compared to the last PR, this part was easier to implement. There might be some other features I can implement, but for the most part, the iOS app is good to go.
