feat(settings): add dock icon visibility setting to desktop settings

- Introduced a new setting `show_dock_icon` in the `DesktopSettings` interface.
- Updated `AppLifecycleSettingsCard` to manage dock icon visibility with a toggle switch.
- Enhanced the API to read and write the new dock icon visibility setting.
- Added corresponding translations for the new setting in both English and Chinese locales.
- Updated tests to ensure the default behavior of showing the dock icon and proper round-trip functionality for settings.
