Protocol fees breakdown

[sunce86]

Description

Implements task 2 1 from #2862:

Extend order_execution with a field that contains a list of executed protocol fees in surplus token, together with the surplus token address

autopilot::domain::Settlement now exposes breakdown of protocol fees in surplus token.

Applies the same refactoring to driver, to keep the code 1:1 (and also to use driver tests to confirm no bugs were introduced).

How to test

Existing tests.

The change described in the description and the actual change in the code seem quite different (likely a rebasing issue?).

I updated the description. Is it ok now?
