• everywhere where a a report is evaluated, use the new report result data structure from OPT-2119 where map reports now return an array

Context:
In a json object the order is not preserved. However, we still use the order of the result e.g. when the user sorts a table. This works in most cases, but there are some edge cases where this just doesn't work. For instance, grouping by an integer variable and then sorting the by key.
