fix(analytics): catalog-gap — heuristic skip-filter for pre-flag prod rows

Prod doesn't write pcat_skipped/pcat_transient yet (sase fd78957 is on
dev), so the 2026-06-11 15:31 run still raised false gaps for Audi
(10/10 rows cold-skip), Hyundai (2/3) and VW (1/3 + 2 untraceable cache
echoes). A real pcat answer needs a network round-trip, so pcat <= 10ms
means skipped — exclude those rows. Verified on prod data: the three
false brands drop below threshold, Renault/Fiat/Honda etc. unchanged.
