Investigate duplicate entries in DB.

I noticed that there was no alert when uploading two identical json files to the DB via add_value_from_json_to_db. The file in question is the photons_per_run.json, which was uploaded to the calibration_devices collection.
This should be avoided by simtools validator.

I think I misunderstood the issue first - this is actually a feature of the DB wand we want to keep this. We can (and want) upload the same model parameters. While reading, we always get the newest one.

This means that if you want to correct an entry, you just upload a new one.

Ok thanks, then I will close the issue.
