Skip AcoustID verification for trusted API download sources

Tidal, Qobuz, Deezer, and HiFi download by exact track ID from official
APIs — files are guaranteed correct. AcoustID fingerprinting only runs
for Soulseek (P2P) and YouTube (extracted audio) where mislabeling is
possible. Users with AcoustID disabled see no change.
