fix(voices): unify default voice set for custom-openai non-kokoro models

Browse source 
Align non-kokoro custom-openai models to use the canonical OpenAI voice set
instead of a separate custom set. Updates logic and tests to reflect this
standardization for improved consistency across OpenAI-compatible providers.
