implement settings, fix bugs and enhance ui

- Added new settings keys in SettingsManager for download path, auto-check updates, auto-raise window, switch to new device, unmount iFuse on exit, theme, and connection timeout.
- Implemented methods to get and set these new settings.
- Updated SettingsWidget to include UI elements for the new settings, including checkboxes and a combo box for theme selection.
- Refactored loadSettings and saveSettings methods to handle new settings.
- Removed deprecated settings UI elements to streamline the interface.
- Introduced VirtualLocation widget for managing virtual location settings with a map interface.
- Integrated QML for map visualization and input handling for latitude and longitude.
- Added functionality to apply virtual location settings to the connected device.
