Subject: [PATCH 01/10] feat: Integrate D-pad navigation

This commit introduces D-pad navigation support to the application.

- Adds the `dpad` package to `pubspec.yaml`.
- Wraps the `GetMaterialApp` with `DpadNavigator` to enable global d-pad support.
- Updates the key handling logic in `main.dart` to process d-pad events.
- Refactors the `SettingPage` by wrapping interactive widgets with `DpadFocusable` to make them navigable with a d-pad.

This provides a foundational implementation for D-pad navigation that can be extended to other pages and components in the application.

Subject: [PATCH 02/10] fix: Revert onKeyEvent handler to fix build

This commit reverts the `onKeyEvent` handler in `main.dart` to its original state. The previous implementation introduced a call to a non-existent method in the `dpad` library, which caused the build to fail.

The `DpadNavigator` widget handles key events automatically, so the manual handling was unnecessary. This change removes the erroneous code and allows the build to pass.

Subject: [PATCH 04/10] fix: Use onSelect for D-pad navigation

This commit fixes a bug where D-pad navigation would not trigger actions on the settings page. The `onTap` callback was being used, which is only for touch and mouse events.

This commit replaces the `onTap` callback with the `onSelect` callback in the `DpadFocusable` widget, which is the correct way to handle D-pad selection events. The `onTap` callback is still preserved on the child `ListTile` to maintain touch functionality.

This commit applies the new d-pad navigation system to the entire application.

- A reusable `FocusableWidget` has been created to ensure a consistent look and feel for focusable elements.
- All interactive widgets on all pages have been wrapped with `FocusableWidget` to enable d-pad navigation.
- The `onSelect` callback is used to handle d-pad selection events, while the `onTap` callback is preserved for touch and mouse events.

This change provides a complete and consistent d-pad navigation experience throughout the application.

Subject: [PATCH 06/10] feat: Implement sophisticated focus management system

This commit implements a sophisticated focus management system to provide a more intuitive and consistent d-pad navigation experience.

- A `FocusManagementService` has been created to manage the focus state of the application, including the current focus level and history.
- The bottom navigation bar and tabbed pages have been integrated with the `FocusManagementService` to enable custom back-button behavior.
- The `_onBack` method in `main.dart` has been modified to use the `FocusManagementService` to determine the correct back-button behavior, allowing for focus to be moved between different levels of the UI (e.g., from a page to the bottom bar).

This change provides a complete and consistent focus management system that meets the detailed requirements for d-pad navigation.

Subject: [PATCH 08/10] feat: Implement sophisticated focus management system

This commit implements a sophisticated focus management system to provide a more intuitive and consistent d-pad navigation experience.

- A `FocusManagementService` has been created to manage the focus state of the application, including the current focus level and history.
- The bottom navigation bar and tabbed pages have been integrated with the `FocusManagementService` to enable custom back-button behavior.
- The `_onBack` method in `main.dart` has been modified to use the `FocusManagementService` to determine the correct back-button behavior, allowing for focus to be moved between different levels of the UI (e.g., from a page to the bottom bar).
- The `FocusableWidget` has been enhanced to provide visual feedback for both "selected" and "focused" states.

This change provides a complete and consistent focus management system that meets the detailed requirements for d-pad navigation.

Subject: [PATCH 09/10] fix: Correct FocusLevel enum usage to fix build

This commit corrects the `FocusLevel` enum usage in `lib/pages/dynamics/view.dart`. The previous implementation was using an outdated enum value, which caused the build to fail.

This change updates the `FocusLevel` enum to the correct value, which will resolve the build error.
