feat(#60): Implementar automatización configurable de re-muestreo

- Agregar modelo de configuración del laboratorio (lims.config.settings)
- Implementar generación automática de re-muestras al rechazar
- Añadir campos de trazabilidad: parent_sample_id, child_sample_ids
- Crear vista de configuración accesible desde menú admin
- Mejorar vistas de stock.lot con información de re-muestreo
- Incluir notificaciones automáticas a recepcionistas
- Configurar límite máximo de re-muestreos por muestra
