refactor(BA-5815): drop REST v2 surface — split into BA-5844

The combined GraphQL + REST landing didn't match the AppConfigFragment
review pattern (BA-5829 GraphQL, BA-5830 REST as separate PRs). Move
the REST handler / registry / path-param wiring out to BA-5844 and
narrow this PR (and its news fragment) to the AppConfigPolicy
GraphQL surface only.
