chore(tests): remove unused _batch_image helper from test_coverage_gaps.py

_batch_image() was defined in tests/test_coverage_gaps.py but never called
in that file — an identical helper already exists in test_image_to_text_node.py
where it is actively used. Dead code with no callers; safe to remove.
