}Start Dynamic Auth Flow
Starts (or restarts) a dynamic auth flow in an existing browser session.
session_id is required in the path. Advances until the next presentation
(decision, form, detection_failed, authenticated, or failed).
If the response is detection_failed with retryable: true, or the request
times out, keep polling GET /v1/identities/dynamic/state/{session_id} —
some login steps take longer than a single start/resolve call. If
detection_failed and retryable is false, open live_view_url to finish
signing in. Do not treat a timeout as a hard stop until view.type is
failed or detection_failed and retryable is false.
