Transaction authorization failures with clear error details

When a transaction authorization fails, you get a structured error with a code and message instead of a declined authorization with no explanation. Provider outcome detail is included when available, so you can respond in your integration or webhooks without treating the failure as unknown.

• Authorization failures return specific error codes and messages you can show customers or use in retry logic.
• Failed authorization responses include processor outcome detail that was previously missing, so reconciliation does not stop on an unexplained decline.
