Add ResultType to InsertResultCommand in all handlers

Added the Type property (ResultType) to every InsertResultCommand sent in PostprocessingBehavior, PreprocessingBehavior, and InvokeRecActionViewCommand. This ensures each result now includes its context (Post, Pre, or Main), both in normal and exception flows.
