Never Donor with limited history

For GiveCampus constituent data and imports.

A Never Donor result cannot establish lifetime first-time status when qualifying older gifts are absent. The calculation reads eligible GC contributions and imported gift types configured for donor status. Standard configuration uses gift presence and fiscal-year buckets, not an arbitrary blank Last Gift Date or Lifetime Giving formula. Supply complete qualifying history or use an authoritative CRM-derived first-time flag/segment with its definition verified. Do not create fictional historical gifts to manipulate status.
