Pull request overview

Fixes the Vehicle Routing quickstart UI tabs by ensuring the vis-timeline components render reliably inside Bootstrap tab panes, and improves the timeline panels’ UX with helpful legends and a clearer summary layout.

Changes:

• Render vis-timelines into dedicated container elements (#byVehicleTimeline, #byVisitTimeline) instead of the entire tab panels.
• Add timeline legends and move the score display into the “Solution summary” table.
• Add score formatting and ensure timelines redraw after data refresh when the relevant tab is currently active.
