Description

This PR adds the functionality to automatically create a UserConfig document in Firebase Firestore after a user signs up in the app.

Key Changes:

• A new method createUserConfig has been added to the AuthStore.ts class.
• After user signup, createUserConfig is called, which creates a UserConfig document in Firestore for the newly registered user.
• The UserConfig collection is initialized with the following default fields:
  • darkMode: false (indicating that dark mode is disabled by default)
  • notificationsEnabled: false (indicating that notifications are disabled by default)
  • language: 'English' (default language setting)

This ensures that each new user has a personalized configuration stored, which can be updated later according to user preferences.
