feat: promote real-time report to normal report

As per #281 (comment)

Wouldn't it be safer to in-fact require a full submit of the mutation report after real-time reporting? If for any intermittent reason a result was not received by the dashboard you would now still have it because the full report is sent after the fact.

We could even use the regular mutation report POST as the trigger to delete any existing real-time results for that version of the report.

Probably, but the scenario you are describing is how it currently works (in the open pull request).

Just checked, this isn't true.. 😅

I'm proposing to move the deletion to the regular POST endpoint, instead of a dedicated deletion endpoint.
