feat(dashboard): reemplazar Load More por paginación con overlay de carga

- Añadir AJAX handlers para paginación en las 3 tablas (búsquedas, clicks, sin resultados)
- Implementar controles de paginación estilo sitio principal (Inicio, números, Ver más, Fin)
- Añadir overlay de carga que mantiene el tamaño del card (sin saltos visuales)
- Estilos de paginación: botones con padding 8px 16px, border-radius 6px, activo naranja #FF8600
- Spinner CSS puro centrado durante la carga
- Deshabilitar pointer-events mientras carga para evitar doble clic
