feat: Add transfer out for Curve

Browse Source 
Add transfer in Executor and pass receiver address in encoding
Remove integration test with StETH pool because we don't support it at simulation level and there is something weird with the amounts (that it is not worth it to investigate now)

--- don't change below this line ---
