chore: suppression du code mort (détection auto, distorsion, ML Kit)

- Supprime 5 services inatteignables depuis l'UI (~3 000 lignes) :
  distortion_correction, image_processing, target_detection,
  opencv_impact_detection, target_rectify
- AnalysisProvider allégé (835 -> ~360 lignes) : retrait de la détection
  par références, de la détection auto d'impacts, du workflow distorsion
  et du doublon moveShot
- Retire les dépendances inutilisées google_mlkit_object_detection et
  google_mlkit_document_scanner du pubspec
- Le bouton ↻ du Plotting efface désormais tous les impacts en un clic
  (clearShots) sans relancer la détection auto ni toucher la calibration
- Nettoie les paramètres morts de TargetOverlay (referenceImpacts,
  onAddShot), le flag _isSelectingReferences, _buildActionButtons vide
  et le résidu _detectionTimer de capture_screen
- Supprime le dossier tests/ (brouillons d'expérimentation OpenCV)
