Add the paste crate to test dependencies to support cleaner test macro expansion for upcoming MuSig2 implementation. Issue: BTC-2652 Co-authored-by: llm-git <llm-git@ttll.de>
Add finalize_input, finalize_mut, and finalize methods to BitGoPsbt to support proper finalization of P2TR MuSig2 inputs. Also export BitGoKeyValue and related constants from the propkv module. Includes comprehensive tests with fixtures to verify proper finalization and transaction extraction. Issue: BTC-2652 Co-authored-by: llm-git <llm-git@ttll.de>
Add structured parsing for Musig2 PSBT extensions: - Participants data - Public nonces - Partial signatures These are now displayed in a human-readable format in the CLI tool instead of raw byte arrays. Issue: BTC-2652 Co-authored-by: llm-git <llm-git@ttll.de>

This PR adds MuSig2 finalization support to our PSBT handling in the wasm-utxo
module:
Add proper parsing for BitGo PSBT extensions including structured parsing
for Musig2 participants data, public nonces, and partial signatures
Add PSBT finalization support for MuSig2 with new finalize_input,
finalize_mut, and finalize methods to BitGoPsbt for proper finalization of
P2TR MuSig2 inputs
Export BitGoKeyValue and related constants from the propkv module
Add paste dependency to test dependencies for cleaner macro expansion in
upcoming MuSig2 implementation
All changes include comprehensive test coverage with fixtures to verify proper
finalization and transaction extraction.
