Route pending action aliases through Agents API

[chubes4]

Summary

• Route Data Machine pending-action list/get/summary aliases through the canonical Agents API pending-action functions.
• Intentionally migrate those Data Machine alias/REST surfaces to canonical Agents API pending-action response shapes as part of the Data Machine 1.0 cleanup direction.
• Extend pending-action Agents API contract smoke coverage with behavioral list/get assertions for the canonical alias shape (preview, agent, creator, metadata.datamachine).

Tests

• php -l inc/Engine/AI/Actions/PendingActionInspectionAbility.php
• php -l tests/pending-actions-agents-api-contract-smoke.php
