LP#2023222: prevent open-ils.fielder.$IDLCLASS from invoking function transforms

This patch adds some argument checking to the family of
open-ils.fielder.$IDLCLASS[.atomic] methods to prevent
JSON query funcion transforms from being invoked. This
is needed to prevent unauthenticated callers from invoking
arbitrary stored procedures.

This is a security patch that closes down a pathway
towards remote, unauthenticated SQL injection attacks.
