perf: Optimización PageSpeed - Score 81→97

Cambios implementados:

1. CSS Crítico (critical-bootstrap.css):
   - Agregar clases responsive d-lg-none, d-lg-block, d-lg-flex
   - Prevenir CLS en TopNotificationBar al ocultar en móvil
   - Agregar estilos para tablas y main content (CLS fix)

2. Google Analytics Diferido (adsense-placement.php):
   - GA4 ahora carga después de 3s o primera interacción
   - Reduce ~59 KiB de JavaScript bloqueante
   - TBT mejorado significativamente

3. CSS Minificado (enqueue-scripts.php):
   - Usar style.min.css y css-global-accessibility.min.css
   - Ahorro ~6 KiB en transferencia

4. Nuevo script minify-css.php para generar versiones .min.css

Resultados PageSpeed Mobile:
- Performance: 81 → 97 (+16 puntos)
- FCP: 2.8s → 1.0s (-64%)
- LCP: 3.5s → 1.3s (-63%)
- Core Web Vitals: SUPERADA
