Pull request overview

Improves Soroban signing confirmations in the Snap by decoding contract identifiers/arguments into human-readable strings and adjusting the confirmation UI layout to better handle long values (addresses, i128/u128, etc.), with copy-to-clipboard support.

Changes:

• Added shared XDR helpers to decode ScAddress, contract function names, and ScVal arguments into readable display strings (with base64 fallback).
• Updated operation/auth-entry mapping and confirmation UIs to render contract addresses and arguments in a copyable, labeled layout.
• Updated i18n strings and expanded test coverage for the new decoding and mapping behavior.
