chore: integrate Hive for local storage management
- Added `hive_ce` and `hive_ce_flutter` dependencies for enhanced local storage capabilities. - Refactored the main application to initialize Hive and migrate existing data. - Updated storage service implementations to utilize Hive for managing application settings and task queues. - Removed the deprecated `StorageService` class to streamline the codebase and improve maintainability.
