integrate ZUpdater & refactor device management and UI components

- Integrated ZUpdater to handle auto updating
- Updated DeviceManagerWidget to improve device selection logic and ensure current device is set correctly when devices are added or removed.
- Enhanced FileExplorerWidget to reset the view when sidebar items are clicked.
- Changed ZIconWidget to inherit from QAbstractButton for better button behavior and removed unnecessary mouse event handling.
- Updated iDescriptor to include device version parsing and improved device version retrieval logic.
- Refactored iFuseDiskUnmountButton and iFuseDiskUnmountButton to use ZIconWidget for a consistent UI.
- Improved iFuseWidget to handle device selection more robustly and update UI accordingly.
- Added SponsorAppCard and SponsorWidget to promote sponsorship within the app.
- Updated ToolboxWidget to streamline device selection and toolbox functionality.
- General code cleanup and comments for better maintainability.
