fix: Native ETH input/output integration tests/fixes

Browse Source 
- Only for single swaps
- Used USV4 for this because it's the only DEX we support that allows native ETH swaps
- For Native ETH input single swaps, we need to properly check the remaining amount (we were treating them wronly like ERC20 tokens)
- For Native ETH output single swaps, we were passing the incorrect currency (the settle always needs to be the out token and the take always needs to be the in token, this should not depend on the zeroForOne value).
