Sync public data-plane OpenAPI spec + parity matrix

[sbg-ci]

Automated sync of the public data-plane OpenAPI spec:

• api-reference/openapi.json — the source Mintlify renders the
  data-plane REST reference from.
• snippets/data-plane-parity.mdx — the local-vs-hosted capability
  matrix the API reference embeds.

API changes in this sync (oasdiff, previous docs copy → current spec):
