Support CoW AMM stats on all chains

[fleupold]

This PR makes it so that statistics for CoW AMMs are chain agnostic. Unfortunately I wasn't able to get the Uniswap graph working our of the box, as it uses different event tables on different chains (and dunes variable syntax isn't flexible enough to choose a target table based on a condition).

Will ask them on tg, but for now we will have to live with CoW AMM performance vs. rebalancing portfolio.

Would the approach in

dune-queries/cowprotocol/accounting/token_imbalances/balance_changes_4021257.sql

Line 241 in d7f5e6b

select * from special_balance_changes_{{blockchain}}

help here?

It is a bit ugly but one can create different tables for different chains and then select the correct one based on a parameter.

This could work. I'm also considering reconstructing the events based on raw logs (which is available in a chain uniform way). However, I think it's ok to have a separate PR for this.

Looks good. Would only update the description at the top of 3959044 and also fix the typo in the description of 4059700

It's usually easier to comment directly on the line that has the typo so that I don't have to guess which one you mean (although it's a good test for my orthographic reading skills). You can even suggest the fix there :-)
