Update behavior namespaces to InvokeAction for clarity

Renamed namespaces in PreprocessingBehavior and PostprocessingBehavior from .Action to .InvokeAction, and updated related using directives in DependencyInjection.cs. Added a folder entry for Common\Behaviors\Action\ in the project file for organization.
