       - Updated test widgets: matrix_widget, answer_options, question_display to use presigned URLs
       - Updated tests_state_manager: converts TestButtonDto and MatrixCardDto to use imageUrl when available
       - All widgets maintain backward compatibility with fallback to ApiConfigV2 URL building
+    - **Test Images Fix**: Fixed missing images in game tests
+      - Fixed matrix question generation: now uses card.image instead of card.id for images
+      - Unified MinIO bucket structure: all images (cards and tests) now use cardImagesBucket
+      - Fixed image conversion logic: keeps image as objectId and adds imageUrl as presigned URL
+      - Removed testImagesBucket - simplified to single bucket for all images
+      - Updated all API endpoints and tests to use unified bucket structure
+      - Added comprehensive unit tests for image conversion in test_manager_image_conversion_test.dart
