Data models changed from earlier releases

[olemartinorg]

Description of the bug

In the ttd/frontend-test app, some (untouched?) data model fields suddenly changed when using a newer version of app-lib-dotnet. This was an unexpected/breaking change.

Steps To Reproduce

1. Switch to use project references in ttd/frontend-test, and point them to the latest main branch in app-lib-dotnet
2. Run the end-to-end test in app-frontend called all-process-steps

Reproduced in v8.3.7 as well. 😢 I can check further back if needed, but seems like this is already out and about in the wild then.

This turned out to be our mistake in app-frontend-react. 🙌 The app we tested here used v8.0.0, and when I upgraded to newer versions (including v8.3.7 as mentioned above), the types got better, not worse. We had in fact initialized our data with empty strings in these cases, so it should be expected that backend stores that for us - not null.
