Add chapter_detail template with events and external URL rendering

New public page template for erfa and chaostreff nodes. Renders the
node's external_url and lists associated events below the page content.

Seed script updated to set template_name: 'chapter_detail' on all
chapter drafts so the template is applied on publish.
