Get pubinfo templates

Returns the basic info of all pubinfo templates. Supports both template identity shapes (docs/template-identity-and-governance.md in the nanodash repo): the label is read off the node typed nt:PubinfoTemplate in the assertion -- the assertion graph URI for legacy templates, the embedded template node for templates with embedded identity -- falling back to the assertion graph URI if no typed node is found. Governed version pairs are deduplicated: a version declaring dct:isVersionOf plus gen:governedBy is listed only if it is the current governed winner of its (kind, space) pair -- the newest non-invalidated version signed by a current member+ of the governing space, with the kind validated as maintained by that space (mirroring the get-latest-governed-version resolver). The winners are materialized once in a single-row group_concat sub-select sharing no variables with the outer query, then checked via string containment; this replaces the previous optional-joined sub-select, which relied on RDF4J's non-standard left-join behavior (under strict SPARQL semantics the unbound cross-join would drop non-governed templates) and risked per-row re-evaluation of the federated SERVICE call. A governed version whose pair does not validate is kept (inert gen:governedBy, matching the resolver's pin-is-the-floor semantics); non-governed versions are unaffected.
