Space-scoped view displays for a single space ref. Derived from list-view-displays (RAfGpyfUX8qjSMN5-aRWOPeVqHajs3f6zUzcnMuRibk1g) but specialised for gen:Space resources: the authority gate keeps only the governing-space-ref hop -- issue #130's reflexive self-edge already exposes the space's own admins/maintainers there -- and drops the agent-self UNION branch, leaving a single non-UNION join under the variable state graph. This avoids the RDF4J planner timeout documented in nanopub-query doc/sparql-quirks.md (variable hasCurrentSpaceState pointer + multi-join + UNION => intermittent 504) that made the space View-displays view fail intermittently. ?ownClass is folded to the constant gen:Space. Takes the same two concrete inputs (resource = space IRI, root_np = ref root) and returns the same columns as list-view-displays.
