Reloads the currently selected page from the PDFium engine, refreshing the page object cache.

• Always check Pdf1.Active before calling page-scoped operations; methods that require an open document raise EPdfError otherwise.

• Class methods (LoadLibrary / UnloadLibrary / GetRecommendedV8Flags) can be called without a TPdf instance.
