feat: variant wizard now creates AND updates existing WC variations

Already synced variants are editable — change price, SKU, image and click
Save & Sync to update them on WooCommerce. New variants are created,
existing ones updated in a single action. Button shows on all products
with variants (purple for new, grey for already synced).
