create-common-widget-from-renderer

Encapsulate the plugin's built-in dataRenderer (custom UI) into a standard public widget so it can be reused by other plugins or features. Core features: (1) extract the UI logic of dataRenderer into standalone component files, (2) register the new components in common_widgets.dart, (3) add data provider functions in _provideCommonWidgets, (4) remove the old built-in renderer code.
