Note

Low Risk
Low risk: this PR only adds a Changesets entry to bump @onkernel/managed-auth-react minor and document the MFA options UI change; no runtime code is modified.

Overview
Adds a new Changesets file to cut a minor release of @onkernel/managed-auth-react, documenting support for rendering mfa_options during AWAITING_EXTERNAL_ACTION so users can choose an alternate MFA method instead of waiting for a push.
