resolveChipDisplayLabel<T> method

String resolveChipDisplayLabel<T>({ required String label, required List<Choice<T>> selectedChoices, required bool singleSelection, required bool hasData, })

• No selection → original label
• Single selection → the selected item's value
• Multi selection → "label (count)"

  required bool singleSelection,
  required bool hasData,

  if (selectedChoices.isEmpty || !hasData) return label;

  return singleSelection
      ? selectedChoices.first.value
      : '$label (${selectedChoices.length})';
}
