HorizontalLineAddingPreviewMobile class

A class to show a preview and handle adding a HorizontalLineInteractableDrawing to the chart. It's for when we're on InteractiveLayerMobileBehaviour.

This mobile preview provides immediate focus mode by:

  • Automatically placing the line at the center of the chart
  • Immediately completing the adding process for instant focus mode
  • Delegating visual rendering to the main drawing for consistency
  • Providing full functionality (drag, neon effects, proper labeling)
