SITO 10f0555c46 feat(poc): expandir POC con datos multilingues, admin pre-creado y guia completa 
- poc/seed.sql: 17 noticias (ES/EN/FR) con traducciones y 25 entidades NER
- poc/poc.sh: corregir VITE_API_URL (faltaba sufijo /api), crear admin con bcrypt
- docs/POC_GUIDE.md: guia paso a paso para que el compañero explore la demo
- README.md: añadir credenciales admin y enlace a la guia POC
