collect signature production and verificaiton in one place (#1179) * collect signature production and verificaiton in one place Signatures are made over data and domain - here we collect all such activities in one place. Also: * security: fix cast-before-range-check * log block/attestation verification consistently * run block verification based on `getProposer` in its own history * clean up some unused stuff * import * missing raises
