The xAI Grok Voice Agent API supports five voices with lowercase names: eve, ara, rex, sal, and leo. The plugin previously exposed a stale list (Ara, Cora, Sage) and defaulted to 'Ara'. Update the GrokVoices type to the current roster and switch the default to 'eve' (the API's own default) so users calling `new RealtimeModel()` with no voice override match the documented xAI behavior.

Voice names are lowercase per xAI's docs, so align the default with the existing behavior (Ara) rather than switching it to eve. Ref: https://docs.x.ai/developers/model-capabilities/audio/voice-agent#available-voices
