Summary
verify() always ran ethers verifyMessage before the EIP-1271 fallback.
Multisig and other contract-wallet signatures are longer than a 65-byte ECDSA signature,
so ethers throws invalid raw signature length (and the catch logs it) even though
checkContractWalletSignature then succeeds.
Skip ecrecover when the signature is not 65 bytes (r||s||v) or 64 bytes (EIP-2098 compact)
and go straight to EIP-1271.
