Fix iterator invalidation issue in RiuPlotWidget::clearOverlayFrames() that caused segmentation faults when accessing QPointer objects during collection modification. The method now safely collects matching frames first, then removes them in a separate loop with proper null pointer checks.
- Refactor PlotShapeItems highlighting in QwtPlotWdiget - s.t. highlighting is not dependent on plotDefinition RimPlot object and its isCurveHighlightSupported flag.
- Remove plot definition assert and utilize guards to allow nullptr/undefined plotDefinition
* #9435 Do not auto update curve appearance during source stepping
