fix: add null check for target in Control and Setting classes

- Added a null check for the target parameter in the check method of the Control class to prevent potential errors when target is undefined.
- Implemented a similar null check in the check method of the Setting class for consistency and error handling.
- Updated FULLSCREEN_WEB_IN_BODY property in Artplayer to true for enabling fullscreen mode in web environments.
