Description
Add OpenAI-compatible auth/header config support to Audio STT/TTS via shared header/cookie handling.
Expose Audio OpenAI config in backend config state and Audio settings UI.
Ensure STT multipart transcription path does not force JSON content type.
Improve STT upload file-handle safety using context-managed file reads.
Added
AUDIO_STT_OPENAI_API_CONFIG persistent config.
AUDIO_TTS_OPENAI_API_CONFIG persistent config.
Audio settings UI controls for OpenAI auth type + custom headers (STT/TTS).
