fix: Pass data in propertyName format to match n8n structure

Problem:
- Data was being passed in normalized 'case' format
- generateConfirmationFormHTML expects propertyName format for normalization
- Form fields were empty because normalization didn't work correctly

Solution:
- Changed StepClaimConfirmation to pass data in propertyName format
- This matches the structure expected by normalizeData function
- Function can now properly normalize data from propertyName to case format
- All fields should now populate correctly
