Refactor Home to SwiftUI

[clemPerrousset]

I have fully refactored the main Home screen to use SwiftUI.

Key Accomplishments:

1. Deleted the obsolete HomeMainViewController folder and the complex HomeV2ViewController along with all its XIBs and cells.
2. Built a robust HomeViewModel and a centralized HomeView implementing the exact visual designs of all the legacy cells (Action, Event, Group, SmallTalk, Pedagogic, etc.) cleanly natively in SwiftUI.
3. Created a hybrid bridge using UIHostingController named HomeViewController, ensuring the new code correctly intercepts and fields all DeepLinks, delegate callbacks (like WelcomeOneDelegate and onboarding handlers), and popups.
4. Addressed several anti-patterns like resolving duplicate initialization, removing runtime UUID() computations in ForEach, ensuring safe optional chains on data properties, and implementing correct view diffing arrays.
5. Successfully cleaned and maintained the Xcode project.pbxproj references to compile locally.
