Pull Request Overview

This PR implements BIP322 proof verification functionality to support validation of message signing proofs in both transaction and PSBT formats. This enables verification of signed messages using Bitcoin's BIP322 standard.

• Adds verification functions for BIP322 transactions and PSBTs with signature validation
• Implements comprehensive test coverage for all verification scenarios and edge cases
• Introduces transaction/PSBT proof verification in the abstract-utxo module
