The CallOffer only advertised GOOD/DEGRADED/CATASTROPHIC. When a
client uses a studio profile, the relay's choose_profile couldn't
pick it. Now advertises all 6 profiles (studio 64k/48k/32k + good +
degraded + catastrophic) in both Android engine and shared handshake.
Also: the relay MUST be rebuilt with the new CodecId variants,
otherwise it will fail to deserialize CallOffer messages containing
studio QualityProfiles in supported_profiles.
