fix🐛: treat a column saved with isQuery "0" as not queryable

The config page saves an unticked query box as "0", and the DTO and API
templates tested IsQuery with a bare if, which is true for any
non-empty string. A column ticked and then unticked became a filter of
the generated list request and a documented query parameter anyway.
They now require "1", as the TypeScript and Vue templates already do.
