fix: Add propertyName to caseJson for iframe form data

Problem:
- Form was empty because propertyName was not passed to iframe
- JavaScript code checked for injected.propertyName but it was undefined
- Only case (normalized) was passed, not the original propertyName

Solution:
- Added propertyName to caseJson object that gets embedded in HTML
- Now JavaScript code can access both case and propertyName
- This allows the form to properly display data from send_to_form_approve.draft
