Guest kiosk checkout for Salt & Stem market bouquets

Salt & Stem walk-up kiosks were creating a Stripe Customer per bouquet (noise in Dashboard, hit Customer create rate limits on Mother's Day). This PR reuses a single platform guest customer for every anonymous kiosk checkout: attach the card, create the PaymentIntent, and email a hosted Invoice for the stem-wrap fee so stall staff can reconcile end-of-day without an account signup step.
