Default widget class spawned for interaction UI when a target or payload does not override it.
The plugin config points this to the bundled /InteractionFramework/Widgets/WB_VerticalInteractionList widget so prompts work immediately after installation. The native fallback is UInteractionUIDefaultWidget if the configured Blueprint class is missing or invalid.
Use this setting for the project-wide prompt widget. Override per target or command through widget payloads when a specific interaction needs a custom visual treatment.
