refactor: invert the last engine-to-UI dependencies

- NodeFactory's menu creation moves to UI-side widget/menu/factorymenu (the factory only exposes its node library read-only now) - DiskManager's cache-settings dialog is created through a registered std::function handler (registered by Core at startup) - OlivePluginInstance creates progress UIs through a PluginProgressReporter interface (Null fallback headless) and queries the active viewer through a provider callback, both registered by Core - factory.h, diskmanager and pluginSupport no longer reference any widget//dialog//panel//window headers or classes
