…adia BBB core sends locale "auto" when the user selects "Auto detect" for live transcription. This value was passed through to Gladia's API verbatim, which rejected it since "auto" is not a valid ISO 639-1 language code. The old bbb-transcription-controller handled this by stripping the language field so Gladia would fall back to server-side auto-detection, but this handling was lost in the migration to LiveKit. - _sanitize_locale() now returns None for "auto" locale - start_transcription_for_user() omits the language param when None, triggering Gladia's built-in auto-detection - update_locale_for_user() sends empty languages list for auto locale - Transcript handlers in main.py resolve BBB locale via the translation map when original locale is "auto" instead of comparing against it
