* feat: implement app icon management and caching mechanism * feat: enhance app synchronization and icon management - Refactored app synchronization tasks to improve structure and clarity. - Introduced shared context for managing app sync state and metadata. - Updated icon handling to ensure proper content type and caching. - Adjusted cache control settings for app icons to extend cache duration. - Improved error handling and logging during app sync processes. * refactor: streamline app icon retrieval by removing unused fileName return - Removed the fileName return value from GetAppIcon function as it was not utilized. - Enhanced the GetAppIcon method in BaseApi to improve clarity and maintainability. - Ensured proper caching headers are set for app icons.
