Set the default OAuth client for an integration auth

Choose which client mints NEW connections when none is picked explicitly (the model-provider setDefaultModel analogue). Selecting one of the space's own clients flags it default; selecting the default the space inherits (the org default, else the system client) un-flags the space's clients so the space inherits it again. Any other client_ref is a 400. Existing connections are bound to the client that minted them and are unaffected. Returns the refreshed clients list. Requires integrations:configure, which is never granted to an API key.
