feat: Refactor and modularize flow handling for improved maintainability

- Extracted BuyModeHandler, DesktopFlow, MobileFlow, and SummaryReporter into separate modules for better organization and testability.
- Enhanced type safety and added interfaces for various return types in Load, Logger, UserAgent, and flow modules.
- Implemented comprehensive error handling and logging throughout the new modules.
- Added unit tests for DesktopFlow, MobileFlow, and SummaryReporter to ensure functionality and correctness.
- Updated existing utility functions to support new flow structures and improve code clarity.
