Add SEO/GenAI structured data and rebuild author profile pages (#784)

Structured data (JSON-LD), built with the repo's dict + jsonify + safeJS
convention for safe escaping:
- DefinedTerm on glossary term pages (all languages, correct inLanguage)
- Article on Educators' Corner posts
- ScholarlyArticle/CollectionPage on the Summaries pages (DOIs are
  extracted from the stored references, never fabricated)
- Person on substantive author profiles

The proposed standalone meta-description partial was intentionally not
added: the theme's site_head already emits description/og/twitter tags
(including from a glossary term's definition), so it would only duplicate.

Author profile pages were broken: content/authors/ was both a content
section and the `authors` taxonomy, so every profile whose term slug
matched its folder name was suppressed, and a junk `authors: - Name "X"`
field in each profile mangled the remaining URLs and titles (pages showed
up as `Name "..."` at /author/name-x/). ~250 such thin pages were in the
sitemap, hurting SEO.

Rebuild:
- Disable the `author` taxonomy + permalink; render profiles as plain
  section pages at /authors/<slug>/.
- Rewrite layouts/authors/list.html to render the profile (avatar, name,
  role, organization, social, bio, interests) plus the author's posts,
  and add an alphabetical authors index.
- Strip the junk `authors:` field and add a proper `title:` across the
  119 profiles.
- Override page_metadata_authors.html so bylines slugify display names
  and link to the new /authors/<slug>/ URLs.
- Noindex empty template-stub profiles (no bio/role/org/interests and no
  credited content) so they don't dilute search.

Note: author URLs change from /author/name-<slug>/ to /authors/<slug>/.
No internal links referenced the old URLs.
