feat: Support out transfer straight to the receiver

- The out transfer is now a responsibility of the Executors -> remove this from router methods
- Also adding a check that the receiver got the full amount out
- In encoding, if it is the last swap, pass the receiver as the trade receiver and not the router address (fix encoding tests)
- Fixed some solidity tests (after rebasing with a PR that is still open, I will fix them all)

TODO: Adapt curve and uniswap v4 to support this
