[Mobile Payments] Restore ability to show tap/insert/swipe card prompt #8116
Description
In #8115, we use waitingForInput as the trigger in CollectOrderPaymentUseCase to show the Reader is ready alert. This may also show when there are specific requests to use a different card read method.
When I checked the code, this was a pre-existing issue, as there was no way for the waitingForInput action to pass on the specific instruction from the SDK, e.g. insert card.
We should restore this ability though, as it looks like it was intended and may cause confusion in the current state.
