Display Query Errors below the Search form area (instead of above)

Summary:
Move the phui-info-view box about Query Errors below the phui-form-view Search form. That's below the `#R` anchor that the view automatically scrolls to. People do not scroll up again to expect an error message up there so show the error message down here.

Closes T16089

Test Plan: Go to http://phorge.localhost/maniphest/query/advanced/ and enter something in the Query field that will trigger a Query Error, such as `help:now` or a very long string. Press the Search button.
