feat(mobile): optimize mobile experience by hiding non-essential features

- Hide live streaming tab in mobile navigation components
- Hide remote input and live stream configurations in settings
- Hide API configuration description text on mobile
- Disable HTTP server startup on mobile devices to save resources

This streamlines the mobile interface while preserving full functionality on tablet and TV platforms.
