Since 67a8080e33
in core, the functionality to bookmark a report from the group
Reports tab has been broken. This commit fixes the issue and adds
system spec coverage to prevent regression.
If a column is payload or contains _payload it will be assumed
it has JSON data in it, then we will show the truncated JSON in the
result column with a button to show the full-screen formatted
JSON using our full-screen code viewer. We also do the same if
the column is the `json` postgres data type.
