Implemented a comprehensive task management system by introducing a dedicated Taskmodel and integrating SharedPreferences for persistent data storage. This update refactors the app's navigation to include a MainScreen with a bottom navigation bar, providing easy access to filtered task views, including active and completed tasks. The user interface was further optimized by extracting task listing logic into a reusable TasksListWidget, applying a consistent dark theme across all screens, and adding custom SVG iconography for a more polished look. Additionally, the task creation process was improved with form validation and dynamic UI updates to reflect changes in real-time.feat: Implement bottom navigation and refactor task management
