feat: implementar compartir protocolos y fármacos específicos + config despliegue

- Añadir botón de compartir en ProcedureCard y DrugCard
- Implementar Web Share API con fallback a clipboard
- Generar deep links a protocolos y fármacos específicos
- Incluir información relevante en el share (título, prioridad, categoría)
- Usar toast notifications para feedback al usuario
- Archivos de despliegue ya presentes en repo:
  - deploy.sh (script de deploy automático)
  - ecosystem.config.js (config PM2)
  - nginx.conf.example (config Nginx)
  - DEPLOYMENT.md (documentación completa)
  - env.example (variables de entorno)
