Build the raw query string from whichever representation the trigger provides.
v2 gives the fidelity-preserving rawQueryString. v1/ALB give an object (single value) and
optionally multiValueQueryStringParameters (preferred, preserves repeated keys). Values are
URL-encoded so repeated/array values survive.
