refactor: streamline cluster node selection logic in configuration components

- Simplified the logic for selecting the master node in both the WzEditConfiguration and WzRefreshClusterInfoButton components by directly finding the master node in the affected items array.
- Removed the intermediate variable for masterNode to enhance code clarity and maintainability.
