<!--

also include relevant motivation and context. Have in mind the following
questions:
1. What is the reason for the change?
2. What is the improvement/solution?

High gas fees are expected if the account has insufficient balance given
the transaction will fail anyway. In extension, we show an alert banner
for this use case. This PR includes the same for mobile.

Fixes: #9117 

## **Manual testing steps**

1. Create a payment request link/QR code using either [MM
deeplink](https://metamask.github.io/metamask-deeplinks/#) or in-app
2. Select an amount higher than account balance
3. See error banner alert for insufficient balance
