payment.failed - WalletConnect Pay Docs

failed is populated. In this example the payment failed before the buyer committed, so processing is null.

`data.status`	Stage objects populated	Stage objects always `null`
`failed`	`failed` (`processing` when the payment had started processing)	`success`, `cancelled`, `expired`, `settled`

Every field is documented in the event overview.
