fix(verify): promote on a live Tier-1 OR Tier-2 source (not T1 only)

Requiring a live manufacturer/encyclopaedia (T1) source never promoted the many
green records sourced from reputable spec/benchmark DBs (gsmarena, cpubenchmark),
so verified stayed at its ~1.2% floor. green already requires a T1/T2 source +
completeness + consistency; accept a live T2 source too. Refs #1
