Add support for custom change wallet functionality in explainTransaction and parseTransaction methods. This allows Bitcoin wallets to send change to a different wallet by providing customChangeXpubs. Includes validation for custom change key signatures in the parsing flow to ensure the change wallet keys were properly authorized by the sender. Added tests for signature verification and rejection of invalid signatures. Issue: BTC-2768 Co-authored-by: llm-git <llm-git@ttll.de>
