This commit uses GroupChooser as the input for param input of type
group_id. Meanwhile, it improves invalid group validation and semantic
error prompts.
* FIX: Wrong type in category_id param input
We will dasherize category_id. The dasherize function accepts a string,
but we don't type-check it, so the default null may be passed in. This
will cause a type error and crash the front-end.
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.
