- Rename verifyBitGoMessageRoundOne/Two -> verifyPeerMessageRoundOne/Two
to reflect that the functions accept any peer party, not just BitGo
- Unify literal union param types (0|1, 0|1|2) to MPCv2PartiesEnum in
getSignatureShareRound{One,Two,Three} and partyIdToSignatureShareType;
add SignerPartyId alias enforcing USER|BACKUP for signer params
- Remove dead runtime assert in partyIdToSignatureShareType (TypeScript
now guarantees valid enum values at compile time) and unused assert import
- Replace if/throw GPG key guard in signRequestBase with assert() for
consistency with surrounding invariant checks
- Add round-2 wrong-type negative test to signTxRequest test suite,
symmetric to existing round-1 wrong-type test
