Reverse lookup: which multisigs does this address sign on
Given a signer address, returns the Safe multisigs it co-signs, across every EVM chain Range’s Safe integration supports (or a single network if given). Squads/Altitude/Realms are not covered yet: their membership lists live inside variable-length on-chain state with no cheap reverse index, unlike Safe’s own owners API.
