test: add golden tests for transaction view across all eras
Implements comprehensive golden tests for the `debug transaction view` command, ensuring consistent output formats across all Cardano eras from Shelley through Conway. These tests validate both JSON and YAML output formats for signed transactions. - Add Test.Golden.Debug.TransactionView module with era-specific tests - Create golden test files for JSON/YAML outputs for all eras - Add signed transaction fixtures for each era (Shelley through Conway) - Test Shelley era transactions with basic inputs/outputs - Test Allegra era with validity intervals support - Test Mary era with native token support - Test Alonzo era with script data hash support - Test Babbage era with inline datums and reference scripts - Test Conway era with governance features (DRep registration, voting) Each era's test validates that the transaction view command correctly parses and displays era-specific features, ensuring backward compatibility and proper format handling across the full evolution of Cardano's transaction formats.
