Create Sharable Entity

Payload for POST /api/svc-registry/sharable-entities.

module must be one of the calling app's registered authorization modules. resourceId is the app-defined identifier — it lives in the sharable_entity:<scope>/<app>/<module>/<resource> FGA object, so it must be a single path segment.

Response body for sharable-entity creation / removal.

Returns the resolved FGA identifiers so callers can audit exactly which tuple was written without re-deriving the path themselves.
