Voice cloning: Lightning v3.1 Pro support

The voice-cloning API now accepts model: lightning-v3.1-pro to clone onto the premium Pro pool, alongside the default lightning-v3.1. Pair the resulting voice_id with the matching TTS model (lightning_v3.1 or lightning_v3.1_pro). The spec and model card previously stated cloning was unavailable on Pro; that was incorrect and is now fixed.
