List Voices

List available TTS voices including system voices and custom voice clones. ?model= is REQUIRED: voice catalogs are per-model and differ in both contents and response shape, so this used to default to inworld-tts-max and silently hand back the wrong catalog once a second TTS model (qwen-audio-3-0-tts) started serving the route. Remaining query params (e.g. ?type=system, ?owner=me, ?gender=female) are forwarded to the worker.
