Fix frontend payment flows: BookingFlow fetch loop, shared TipPayment, card icons, terms route

Fix the P0 infinite refetch in BookingFlow (payment-methods fetched once via a guard flag, was looping on empty saved-card arrays and DoS-ing the rate limiter). Extract the shared TipPayment component so tip and pay-tip routes no longer drift; reconcile formatTimeRange override_duration_minutes and subtotal/tipsPaid. CardBrandIcon gains the correct Square enum keys (DISCOVER_DINERS, CHINA_UNIONPAY). PaymentModal reads card_last4. Login links resolve to the new /terms and /privacy-policy routes. Add frontend/.env.example.
