feat(analytics): Dashboard v2 con recomendaciones accionables y UX mejorada

- Agregar KPIs con tendencias vs período anterior (↑↓% comparativo)
- Implementar secciones de recomendaciones: Contenido a Crear, CTR 0%,
  Quick Wins, Contenido Estrella, Contenido en Decadencia
- Convertir listados a tablas con columnas separadas para mejor legibilidad
- Agregar botones Editar + Ver en todas las tablas de posts
- Ocultar secciones vacías dinámicamente (Búsquedas Sin Resultados)
- Relajar criterios Quick Wins: pos 2-15, CTR ≥2%, búsquedas ≥2
- Incluir distribución de clicks por posición con barras de progreso
- Agregar exportación a Markdown para análisis con IA

Archivos nuevos:
- admin/class-analytics-dashboard.php (UI del dashboard)
- admin/class-metrics-repository.php (queries de métricas)
- admin/assets/dashboard.css (estilos Bootstrap 5)
- admin/assets/dashboard.js (interactividad y export)
- sql/create-indices.sql (índices para optimización)
