We also need to change this in infrastructure repo right?

Description
Our implementation of the cow amm helper contract needed to generate rebalancing orders was very slightly different from the agreed upon interface. This difference prevented us from indexing balancer pools correctly. To support the legacy and balancer pools at the same time both factory implementations need to adhere to the exact same interface (actually just the emitted events).
This PR updates the interface and all related deployment info based on cowprotocol/cow-amm#99.
Changes
Also the new helper contract returns a slightly different signature which already includes the signer address (expected by the settlement contract). This should generally be nicer for people using the helper but in our code base we expect the signer address to not already be part of the signature bytes so we needed to introduce a small workaround (with comment explaining why).
Note that the helper contract for the balancer implementation has the same behavior so everything should work out.
I also removed the deployment information for
sepoliasince the helper contract actually supports 0 pools there so we might as well drop it altogether onsepolia.How to test
e2e tests still work
