This PR does not have a breaking change. It was created to remove the reference to timestamps in inputs key of analysis results. The timestamps key was removed in the backend through the PR https://github.com/vikinganalytics/vibium-cloud/pull/793. In MVG, the timestamps key is referenced only in the tests.

It looks like the mock data of analysis results in the MVG repository is outdated. This PR should instead make sure the structure of all stub data conforms with the structure defined in the backend.
