Refactor authentication and session management

- Removed old llm_login and session scripts, replacing them with a new structure for handling SSO login and session management.
- Introduced a new prompt system for collecting SSO redirect URLs, ensuring compliance with security protocols.
- Implemented a robust backend notification system for tracking scan initiation.
- Enhanced browser profile configuration and resource management for improved session handling.
- Added utility functions for environment variable checks and logging.
- Updated the overall architecture to improve maintainability and readability.
