use enum instead of string for payment status

[Musfick]

Using String

status == 'paymentSuccess'
status == 'paymentFailed'
status == 'paymentError'
status == 'paymentClose'

Enum

enum PaymentStatus {
  Success,
  Failed,
  Error,
  Close
}

Using enum

switch (status) {
    case PaymentStatus.Success:
      // do something
      break;
    case PaymentStatus.Failed:
      // do something
      break;
    case PaymentStatus.Error:
      // do something
      break;
    case PaymentStatus.Close:
      // do something
      break;
  }

Now we are changed the payment functionality, now you can use it as tokenized based payment.
