Crash on New User Signup (Friends List 404) #675
Description
🐛 Describe the bug
When a new user signs up and logs in for the first time, the application throws an unhandled exception and immediately redirects back to the Welcome/Login screen instead of proceeding to the Home screen.
The Cause: Upon login, the FriendsController initializes and attempts to fetch the user's "Friends List" document from the Appwrite database. For a brand new user, this document does not exist yet. Appwrite returns a 404 Document Not Found error.
The current code treats this 404 as a critical failure instead of a valid "empty" state. This exception causes the user profile initialization to fail, triggering the catch block in auth_state_controller.dart, which forces a redirect back to the WelcomeScreen. It also triggers a secondary No Overlay widget found error because it attempts to show an error Snackbar during the screen transition.
lib/controllers/friends_controller.dart. The getFriendsList() method does not handle the 404 case for new users.
Steps to Reproduce:
Run the app on a fresh install (or clear app data).
specific user signup flow to create a new account.
Observe the crash/redirect immediately after clicking "Sign Up".
