chore: align route-engine with route-graphics 1.0

[han4wluc]

Summary

• align route-engine authored event payload config with the published route-graphics 1.0 payload interface
• update the VT sync default to route-graphics@1.0.0 and keep the VT render-complete/framebuffer behavior aligned with the passing VT path
• replace legacy generic easing names in route-engine schema/specs with the explicit easing names accepted by route-graphics 1.0

Testing
