Replace vote-only sigmoid with a blended votes+popularity score in
aurSortByMetric. AUR's Popularity field (already stored and populated
from the API) is a time-decayed vote score that better reflects current
relevance than raw NumVotes alone.
Falls back to votes-only when popularity <= 0 (brand-new packages).
Uses the same sigmoid normalization pattern as the existing minVotes
constant (minPopularity = 0.5).
Side effect: AUR packages no longer artificially outscore repo packages
via historical vote counts when separateSources is disabled. Updated
two noseparatesources test expectations accordingly.
