fix(engine): force full board repaint when the decor-view poller fires (#130)

The #152 poller fixes resolution + layout on a missed fold/unfold, but
a transient clip could survive if card sprites held stale visuals after
geometry converged. Emit StateChangedEvent alongside the synthetic
WindowResized so card_plugin re-renders every sprite from scratch —
silent self-heal, no player-facing prompt.
