able to create forms and view forms correctly

1. paste the json in form builder and create
2. open form

### Project Identifier

_No response_

### Additional information

_No response_

Start with the form builder and the form-opening flow, using the three JSON examples and the listed reproduction steps. Verify the nested-object crash, the [object Object] display, and the third screenshot's behavior. Done means these forms can be created and opened with their values rendered correctly.
