The propagation_scores → binary files cutover dropped the factors
JSONB column, which left point_detail returning factors: %{} and
broke the analysis breakdown popup on map clicks. Persist the
enriched f00 grid_data to /data/scores/profiles/{iso}.etf.gz and
rescore on demand at click time so the factor block renders again.
