Rework investigation selection processed data

When we ingest processed data, we search for the investigation of the raw datasets

• currently we take the investigation of the first raw dataset => select the most recent of all raw datasets?
• for mx use cases, we limited the selection investigation to the last 90 days. We could either limit by the number of investigations retrieved or in the time. We can also extract the session date from the path and search for the session. If not found, we fall back to the current mechanism
