[FEAT][CV] Label Ambiguity

Add Label Ambiguity check, based on Similar Image logic -
Meaning, similar images with conflicting labels.
Think of how this should be applied for object detection - probably comparing bboxes?

Reuse as much code as possible with SimilarImageLeakage and LabelAmbiguity (tabular) if possible

Start by reading the existing SimilarImageLeakage and tabular LabelAmbiguity checks to understand their shared logic. Then determine how conflicting labels should be identified for similar images and whether object-detection bounding boxes must be compared. Done means the intended behavior and reusable implementation scope are defined and covered for the relevant image tasks.
