refactor(tauri): improve script handling in execute function for Tauri

- Updated the `execute` function to simplify string handling by passing strings as-is, allowing Rust to manage proper escaping.
- Adjusted related test cases to reflect this change, ensuring accurate expectations for string arguments passed to the plugin.
