test: 5-hop Multi-protocol integration test

- Needed to add ekubo and uniswap v4 to callback-limited protocols.
- I had to bump the fork block in all of our integration tests: The way it was before meant that certain integration tests were using certain executor addresses, and others were using different ones, because of the redeployment. This was a pain to account for on the rust side. Instead, all tests now use an Ekubo-compatible fork block. Values needed to be updated because of price changes between blocks.
