Add verification capabilities for BIP-322 message signatures created with wasm-utxo. Implement test cases for signature validation across both p2shP2wsh and p2wsh script types. Also add support for verifying multiple inputs in a single PSBT. Issue: BTC-2916 Co-authored-by: llm-git <[email protected]>
Remove nonWitnessUtxo check when verifying BIP322 signatures, since the txid check in assertTxInput already ensures the input references the correct to_spend transaction. Issue: BTC-2916 Co-authored-by: llm-git <[email protected]>
Use the wasm-utxo implementation for BIP322 message verification instead of utxo-core. This includes handling PSBT and transaction proof verification with the new API. Issue: BTC-2916 Co-authored-by: llm-git <[email protected]>

This PR adds support for verifying BIP-322 message signatures using
the wasm-utxo implementation instead of utxo-core. The implementation:
with wasm-utxo
and p2wsh script types
checks, since the txid check in assertTxInput already ensures correct
references
