refactor(frontend): simplify NodeDataRenderer output handling

### Changes
- Removed unused `useNodeStore` and `useShallow` imports from `NodeOutput.tsx`.
- Simplified the mapping of output data in `NodeDataRenderer` by directly using `latestOutputData` values.
- Updated the `handleCopy` function to use the simplified value variable.

### Impact
- Streamlines the output rendering logic, improving code readability and maintainability.
- Reduces unnecessary dependencies, enhancing performance.

### Testing
- Verified that the output rendering remains consistent with the latest execution results.
