Pull request overview
This PR refactors the Google and Apple sign-in flows to simplify the authentication architecture by removing the intermediate sign_in_with_auth_credential_use_case and directly handling Firebase authentication within each provider-specific use case.
Changes:
- Separated loading states for Google and Apple sign-in buttons
- Consolidated sign-in completion logic into a single
_signInCompletionmethod - Removed intermediate credential handling use case and integrated Firebase sign-in directly into provider-specific use cases

The updateCurrentUser is called twice - once inside signInCompletionUseCase (line 31 of that file) and again here. This creates a redundant database write operation. Remove the call from either location to avoid duplication.

The loading state flag is not reset to false when an exception occurs in _signInCompletion. This causes the button to remain in a loading state after a sign-in error. Wrap the call in a try-finally block to ensure the flag is always reset.
