List Partner Shared Connections
Lists shared copies of a connection owned by a specific organization in the partner account.
The `org_id` must match the organization that owns the parent connection. If it
does not, the endpoint returns `404` rather than exposing information about the
parent connection.
This endpoint is useful in partner workflows where the parent connection is in
the partner owner organization and the caller needs to audit which child
organizations already have a shared copy.
