 * Step 15 — Confirmation / Plan View for the FA arrangement wizard.

 * Terminal confirmation page. Different copy for at-need vs pre-planning.
 * Confirming and orienting — not celebratory.
 *
 * At-need: "Your arrangement has been submitted" + callback info
 * Pre-planning: "Your plan has been saved" + return-anytime info
 *
 * No progress indicator. No back button. Links to post-plan flows.
 *
 * Pure presentation component — props in, callbacks out.

 * Spec: documentation/steps/steps/15_view.yaml
