style: Restaurar esquema de colores en páginas de auditoría

- Cambiar funciones de color de grayscale a colores semánticos:
  * getActionColor: delete (red), update (blue), login (indigo), create (green)
  * getSeverityColor: critical (red), high (orange), medium (yellow), low (blue)
  * getStatusColor: active (blue), resolved (green), investigating (yellow)
  * getRiskColor: safe (green), low (blue), medium (yellow), high (orange), critical (red)

- Actualizar botones a esquema indigo del proyecto:
  * Botones de período de análisis: bg-indigo-600
  * Paginación: bg-indigo-600 para página actual
  * Botón actualizar: bg-indigo-600
  * Botón ejecutar acción: bg-indigo-600

- Botones de acción con colores apropiados:
  * Bloquear IP: bg-red-600 (acción crítica)
  * Resetear contraseña: bg-orange-600 (acción importante)
  * Notificar admin: bg-blue-600 (acción informativa)

Mantiene consistencia con el estilo visual del proyecto.
