fix(analytics): catalog-gap — ignore rows where pcat never evaluated

'No catalog — identified as X' rows produced during a pcat cold-pool
skip, transport blip, or open circuit breaker are not evidence of a
coverage gap; counting them raises false brand-gap insights (Audi,
2026-06-11). Excludes rows carrying the new pcat_skipped /
pcat_transient markers (sase.tr dev fd78957) or pcat_circuit_open.
