Fix SEO inconsistencies: founding year, accuracy rates, sitemap, alt text

- Fix founding year from 2018 to 2015 across about.php, organization-schema.php, and index.php schema
- Standardise data accuracy rate to 99.8% across about.php and services/web-scraping.php (was 99.7%/99.9%)
- Remove google-oauth-callback from sitemap.xml
- Fix UK Gambling Commission logo alt text (remove misleading 'regulatory compliance' label)
