fix: pipeline health — stuck docs, price fallback, sentiment normalization, signal-engine scale, quality gate

- Scheduler: lower stale threshold 240→30 min, batch limit 100→500, TTL 14400→3600 - Prediction snapshot: add 24h market_snapshots time-window fallback - Aggregation: add normalize_impact_scores() z-score normalization - Helm: signal-engine replicas → 0 (idle when dual pipeline disabled) - Quality gate: max_snapshot_age_hours 24→48 - Add backfill script for NULL price_at_prediction snapshots - Add PBT bug condition and preservation tests (14 tests)
