feat: Make boolean quirk an enum

[provokateurin]

For query parameters we have to convert booleans into integers as they are only accepted that way. This sets the enum field on the returned integer schema to indicate that these are the only possible values. Can be tested in the server.

Fixed

The problem is that query parameters are always interpreted as true unless the value is 0. So we need to map them as integers :/

The problem is that query parameters are always interpreted as true unless the value is 0.

But not when you POST a JSON body, but it will work in both cases anyway, so okay

Yes with a json post body boolean works fine, but not with the query parameters as we use them here.
