Suppression éclairage solaire, GPU accéléré, --file multi, tests unitaires

- Suppression de generate_solar (éclairage solaire) des visualisations
- Accélération GPU de hillshade, slope, aspect, curvature, depressions,
  anomalies, roughness, texture GLCM, flow (sink filling)
- Nettoyage mémoire GPU entre visualisations (gpu_cleanup)
- Correction OOM texture GLCM: calcul entropie bin par bin au lieu d'un
  tableau 3D massif sur GPU
- Correction bug: xp_minimum_filter manquant dans imports visualizations
- Option --file accepte plusieurs noms complets sans extension
- run.sh affiche l'aide si appelé sans arguments
- Option --test pour exécuter les tests unitaires dans Docker
- Filtre ReturnNumber>=1 intégré dans le pipeline PDAL (plus d'erreur SMRF)
- 60 tests unitaires: GPU, visualisations, rendering, DTM, pipeline, CLI
- Ajout pytest au Dockerfile
