Refactor authentication flow in GraphApiClient to improve token retrieval and logging

- Removed inline comments for clarity and added console logs for better debugging during the OAuth process.
- Updated the handling of the redirect and navigation events to streamline access token extraction from cookies.
- Implemented a new method to manage callback handling, ensuring proper closure of the authentication window and error handling.
- Enhanced logging for navigation and redirect events to provide better visibility into the authentication process.
