feat: implement Google OAuth support for Android and iOS

- Added support for Google OAuth with separate client IDs for Android and iOS.
- Updated `verify_google_id_token` to validate `aud` against both client IDs and check `email_verified`.
- Modified `google_oauth_handler` to accept and process the new client IDs.
- Enhanced security by enforcing explicit JWT algorithm validation.
- Updated mobile app to handle Google OAuth flow using `expo-auth-session`.
- Fixed API request to send `id_token` in snake_case as expected by the backend.
- Added necessary environment variables for Google client IDs in mobile app.
- Implemented intent filter for Google OAuth redirect in AndroidManifest.xml.
