/**
 * Get the QuestionnaireResponse index of every rendered repeating group instance, in rendered order.
 * An instance with no QuestionnaireResponse counterpart gets `null`.
 *
 * Instances that are still empty (added via "Add Item" but never filled in) hold a null `qrItem` and
 * are dropped when RepeatGroup builds its QuestionnaireResponse items, so an instance's rendered
 * index is not its index in the QuestionnaireResponse. Validation walks the QuestionnaireResponse, so
 * instance-scoped error keys must use these indices instead.
 *
 * Computed for the whole list in a single pass, so callers rendering n instances stay linear rather
 * than re-scanning the preceding instances once per instance.
 *
 * Keep this in sync with how RepeatGroup projects `repeatGroups` into `onQrRepeatGroupChange`.
