Remove fabricated proof from the homepage and the six language homes

- Deleted the three invented testimonials (María González / 'EMPERATRIZ DIGITAL',
  Alejandro Ruiz / 'COMANDANTE DE OPERACIONES', Carlos Salinas / 'GENERAL DE
  TECNOLOGÍA'). The companies do not exist and the quotes are not attributable.
- Removed the ISO 27001 and SOC 2 trust badges: they claimed *we* hold those
  certifications. Third-party statements about Hetzner/Azure/Odoo SH being
  certified are factual and stay.
- Removed the placeholder phone number (tel:+) used as a 'Call now' button on
  all six homepages.

E-E-A-T and legal exposure, not a ranking play.
