Add SeparationLineComponent for visual separation in charts (#419)

* Add SeparationLineComponent for visual separation in charts

This commit introduces the SeparationLineComponent, which provides a styled separation line for visual clarity between chart sections. The component includes its own CSS for styling, an HTML template, and a basic spec file for testing. The component is utilized in the label-chart component to visually distinguish comparison charts.

* Fix import statement to use double quotes for consistency
