wvs_map: bake title + repo attribution inside the axes, add top headroom

Draw the title and github.com/wassname/moral-maps note in the empty bottom-left
INSIDE the axes so a crop can't strip attribution and there's no whitespace band.
Give the models overlay extra top headroom so the most-secular model stars and
their labels seat inside the frame instead of spilling above it. Regenerate PNG+SVG.
