Fixes#1202
I had to revert the loader changes that switched from/to as it was causes quite a lot of logistical complexity. Instead of using Loaders, we are setting the type of account (account or contact), and it is being displayed appropriately. There is a very slight deviation from the design, however it is consistent with the design for other transaction previews.
feat: add BalanceValidator
Shows an exclamation icon next to the "from" account when the balance for the requested asset is too low.
This is useful when the user starts the transaction wizard on the TransactionPreview step.
