FASE 7d: Lazy Loading + Minificación + Auto-serve minified

Cambios implementados:

1. Lazy loading de imágenes:
   - catalog.js: loading="lazy" decoding="async" en part cards y detail panel
   - inventory.js: lazy loading en imagen de detalle de item

2. Minificación de assets:
   - scripts/minify-assets.sh: minifica JS (terser) y CSS para POS y Dashboard
   - 25 archivos .min.js + 5 .min.css generados en pos/static/
   - 14 archivos .min.js + 8 .min.css generados en dashboard/

3. Nginx auto-serve minified:
   - try_files $1.min.js antes de servir .js original
   - try_files $1.min.css antes de servir .css original
   - Transparente para los templates HTML (cero cambios en HTML)

4. Cache warming script:
   - scripts/warm_vehicle_cache.py: pobla Redis con vehicle info por batches
   - Mitiga DISTINCT ON + 4 JOINs sobre 2B filas
   - Corre en background, procesa ~1.5M parts

Tests: 73/73 pasando
