Uploading json of the older version report tool empties findings

[julezrulez]

Describe the bug
When saving a report with findings as a json file with old september2021 Version 2.0.3.
and opening the same json with the current version: 18 July 2025, Version 3.0.3
all findings are gone.

To Reproduce
Steps to reproduce the behavior:

1. Go to WCAG-EM Report Tool Version 2.0.3
2. Add some findings in step 4 and use the Passed/Fail/Checked field.
3. Save the report to a json-file
4. go to WCAG-EM Report Tool V3.0.3
5. Open the json you just saved with version 2.0.3.
6. Go to step 4 and find the findings. -> they are gone.

Expected behavior
I would have expect ll fields were still filled.

Additional context
This used to work a couple of years ago. I am for sure that I have tested it.
I think that the problem lies in the renaming of field-id's.
