Affiliate funnel: tag all odoo4projects.com links with utm_source=odoo-expertos.com

- 467 outbound links across 254 files now carry our affiliate UTM
  (replaces the stale utm_source=X5Y2I933 on the banner components)
- fix 36 links to /starter /professional /enterprise /business /mx,
  which return 404 on the target; remapped to /#pricing
- add a managed-hosting CTA block to all 6 homepages (es/en/de/fr/pt/ar),
  which previously carried zero links to the host
