test: add send DAI spec using Anvil state

[seaona]

Description

In this PR, I add a new spec for Sending DAI, leveraging Anvil state injection.
This is the base work for changing the Swap specs to use this approach instead of Tenderly. Another PR will follow up with a Swap spec using the same approach.
