Research globally handling of viem errors

[iamacook]

Description

In general, we have a pattern whereby we don't expose external packages beyond the datasource layer. This not only allows interchanability, but also consistent error handling.

Due to the extensive functionality of viem, it is the only package that doesn't follow this pattern. We have already seen two instances where this has thrown unknown errors, breaking the UI:

• Fix getAddress unhandled error in TransactionsService #1621
• Handle malformed multiSend decoding errors #1984

We should investigate wrapping viem with consistent error handling, not using the package directly.

Requirements

• Assert the best way to wrap viem. (Defining our own interface for this would be tedious, but possible.)
• If viable, wrap viem accordingly.
