Set connector credentials

Set or rotate the connector's credentials in place: `kind: api_key`, `kind: oauth` (client credentials) or `kind: certificate` (mTLS client certificate). Meta has no call that removes a credential layer; change the connector's `auth_type` or delete it instead.

Get connector failure logs

Third-party failures over the last 7 days (window at most 7 days, default the last 24 hours). Each entry carries `failure_code_name` and `error_message`.
