The committed openapi.json (version 1.12.1) no longer matches
the live spec at https://opendpp-node.eu/openapi.json (version 1.12.0).

Refresh the kit from the source of truth: re-copy openapi.json (and regenerate the
samples/ if the emitters changed) from the OpenDPP product, then update CONFORMANCE.md
and CHANGELOG.md.
