fix(rectification): deliver range cards on tied first place instead of falling back to collect (BUG-680/681/682)

Refresh persist failures no longer count as attempts. tied_first completes with a range before stillNeedNarrowing. Delivery narration and cards share DELIVERY_OUTCOMES. The question gap gets a delivered terminal so the unavailable copy does not appear after a range is given.
