Fix: One way train run arrows are drawn outside of lines when moving node (#591)

* Fix: When dragging a node, the train route section is displayed very abstractly—just as a line. As soon as the node is dragged, the full detail display is applied. This ensures high drag performance and prevents elements that have not yet been fully updated (recalculated) from being displayed incorrectly. This means that not everything always needs to be fully updated when dragging, which further improves performance.

* Fix: Add filter to groupLinesEnter: render arrows only for non-round trips

* fix: npm run format

* Update src/app/view/editor-main-view/data-views/trainrunsections.view.ts

Perfect! Really nice spot. Thanks a lot
