Introduces ReservationSuccess, ReservationFailed, PurchaseSuccess, PurchaseFailed, TicketSmall, and TicketList components for handling and displaying reservation and purchase outcomes. Updates order flow logic in OrderComponent to support reservation and purchase states, disables/enables form inputs during submission, and integrates new UI feedback. Also adds angularx-qrcode dependency and updates @infinimotion/model-frontend version.
