/**
 * Fixes from the Seobility crawl of 2026-11-10 (1,094 pages).
 *
 *  1. Placeholder SEO title "Title for search engines [seo_title]" on /solutions.
 *  2. News records whose title/path_segment were saved twice in a row.
 *  3. News path_segments that contain slashes (imported from old URL paths).
 *  4. Typos reported by the crawler (content tables).
 *  5. Second wave of dead old-site links: /resource-center, /services,
 *     /contact-sales, /aetria-use-cases, /video-wall-solutions, absolute
 *     datapath.co.uk / datapath-us.com links and tracking-parameter variants.
 *  6. "http://www.vitec.com./" (trailing dot) links.
 *  7. Redirects: record shells (/product, /news/article, /success-stories/
 *     story) onto their overviews, plus a few orphaned product URLs.
 *  8. Meta description for /datasheets.
 *  9. WordPress remnants inside the 17 SEO articles (lazy-load placeholder
 *     images, leftover script fragment, wp-/data- attributes, bare text).
 * 10. News records of type "internal page" pointing at the old /en/news
 *     pages: their body lives only on those pages (which now redirect onto
 *     the empty article URLs). The page content is copied into the record,
 *     images become fal_media, the record becomes a regular article, and
 *     every old page gets its 301.
 *
 * Dry run:  php migrations/seo_report_fixes_20261110.php
