Note

Low Risk
Documentation-only update describing an additional invite option; no product logic or data-handling code changes.

Overview
Updates the SSO FAQ to document that subaccount users can be invited with password-based authentication on SSO-enabled accounts via the new "Allow password-based authentication" checkbox (avoiding the previous create-then-disable workaround).

Adds a dedicated FAQ entry for this scenario, includes a screenshot (media/sso/allow_password_auth_checkbox.png), and refreshes the page lastUpdated date.
