feat(places): ItemList and BreadcrumbList, and the e2e gate

ItemList tells Google the page is a ranked set rather than prose;
BreadcrumbList puts the place in a hierarchy. School URLs in the markup are
absolute on the canonical host, since a relative URL in JSON-LD is ambiguous.

Eight journeys covering all four families, the two-namespace guarantee, the
threshold, the canonical, the sitemap and the local-versus-England line — the
last because that comparison is the reason these pages are not a name dropped
into a template.
