Implement GUI Automation Test Commands and Refactor AsarWrapper Usage

- Added new test commands for GUI automation in `test_commands.cc`, including handling test runs, statuses, listings, and results.
- Refactored instances of `app::core::AsarWrapper` to `core::AsarWrapper` across multiple files for consistency.
- Updated CMake configuration to include new test command files.
- Modified integration and unit tests to reflect the changes in AsarWrapper usage.
- Ensured proper error handling and output formatting for test commands.
