Adds "✨ Auto Pairs erstellen" button to the PairsPanel. On click,
sends the image and all object coordinates to Claude Haiku, which
returns 30 structured pairs (10× text, 10× yes_no, 10× question,
each split easy/medium difficulty) as JSON. Pairs are then created
and linked via the API with a live progress indicator.
