CSVAlt field carry-through fix - 22 May 2026

Problem found:
The Outscraper importer output CSV contains phone, address, rating, reviews_count, google_maps_url, opening_hours/opening_hours_json, emails and socials. However the URL SEO ARTICLES to CSVAlt export format only exports fixed CSVAlt columns: name, slug, description, content, tags, categories, status, Is Featured, Image and Format Type. Therefore business-specific fields do not appear as separate columns in the CSVAlt output.

Fix applied:
1. Imported emails and socials are now stored into outscraper_businesses.extracted_emails and outscraper_businesses.extracted_socials.
2. The generated URL SEO ARTICLES CSV content field now includes a Business contact and Google details section containing:
   - Business phone
   - Business address
   - Google rating
   - Google reviews count
   - Google Maps URL
   - Official website
   - Emails
   - Socials
   - Opening hours as raw JSON inside <pre>
3. Existing generated/imported URL SEO ARTICLES must be re-created from the new exporter output to show these details in the later CSVAlt export.

Files changed:
- outscraper-url-seo-importer/includes/outscraper-functions.php
- README-INSTALL.txt notes
- sample CSV headers now include optional emails,socials columns
