// attach up to 2 badges (outline chips) to a "Text with Image" ad, so the
// column becomes a JSONB string array (renamed badge_labels to match the
// plural shape, mirroring the existing `ctas` JSONB column). Any existing
// scalar value is wrapped into a single-element array; null/empty becomes [].
