fix(frontend): Prevent node drag when selecting text in object editor key input (#11955)

## Summary
- Add `nodrag` class to the key name input wrapper in
`WrapIfAdditionalTemplate.tsx`
- This prevents the node from being dragged when users try to select
text in the key name input field
- Follows the same pattern used by other input components like
`TextWidget.tsx`

## Test plan
- [x] Open the new builder
- [x] Add a custom node with an Object input field
- [x] Try to select text in the key name input by clicking and dragging
- [x] Verify that text selection works without moving the block
