feat: Don't take protocol fee for in-market limit orders

[sunce86]

Problem

We don't want to take protocol fees for limit orders with in-market price.

Suggested solution

Don't define protocol fee policies for limit orders with in-market price. To determine if the price is in-market or out-of-market, already existing functionality can be used: https://github.com/cowprotocol/services/blob/main/crates/autopilot/src/solvable_orders.rs#L558

Additional context

Dependent on #2084 which needs to be tackled first.

Acceptance criteria

• Protocol fee is not taken for limit orders with in-market price (where price is determined at the moment the order was created).
