[Bug]: Predict: issues with gasless on source deposits

[bschorchit]

Describe the bug

We're showing users the error that you need ETH for gas, when the user has no ETH.
Instead, we should quote the gasless route and show the user "the add less than $x" error with how much they can deposit with that token to also cover for gas.

@bschorchit We can't know the gasless cost unless the user has balance at the end of the simulated transaction, otherwise no gas fee token is returned, meaning this isn't currently possible.
