Add PostprocessingBehavior for action result logging

Introduced PostprocessingBehavior as an IPipelineBehavior for InvokeRecActionViewCommand. This behavior handles post-processing by executing optional queries, serializing results, and logging outcomes via InsertResultCommand. It also manages error handling based on the action's ErrorAction setting, ensuring consistent result tracking after command execution.
