Debug (static) Listing Builder listing query with var_dump() of SQL in Dev mode

<!--
In the listing's Display tab in Dev mode, add the following to var_dump the SQL of the listing query.
This can be handy for seeing the SQL of a static listing, for which Debug Mode (FWP.settings.debug.sql in the Console) will not work.
