apiClient.get returns the raw JSON body { data, cacheMeta }, so callers
were storing the envelope in state and reading totalScore as undefined,
crashing ListingDetailClient via undefined.toFixed(1).
Unwrap .data inside getNeighborhoodScore so consumers receive the bare
NeighborhoodScoreResult as the existing type expects.
