Tests for pSEO article noindex feature.

Covers:
- NOINDEX_THRESHOLDS: lambda functions evaluate correctly per template
- Sitemap excludes articles with noindex=1
- Article detail page emits <meta name="robots" content="noindex, follow"> for noindex articles
- Article detail page has no robots meta tag for indexable articles
