End zones: bubbles

Zone counts as size-encoded bubbles on the pitch, instead of plot_zone_heatmap()’s color-encoded grid. Size is a more intuitive read of “how many” than a color ramp – no legend needed to compare two bubbles’ areas – at the cost of precision for zones with close counts, where a heatmap’s exact color-to-value mapping does better. Each bubble carries its own count label, so that trade-off costs nothing here.
