fix(gateway): STT config resolution, stream consumer flood control fallback

Browse Source 
Three targeted fixes from user-reported issues:

1. STT config resolution (transcription_tools.py):
   _has_openai_audio_backend() and _resolve_openai_audio_client_config()
   now check stt.openai.api_key/base_url in config.yaml FIRST, before
   falling back to env vars. Fixes voice transcription breaking when
   using a custom OpenAI-compatible endpoint via config.yaml.

2. Stream consumer flood control fallback (stream_consumer.py):
   When an edit fails mid-stream (e.g., Telegram flood control returns
   failure for waits >5s), reset _already_sent to False so the normal
   final send path delivers the complete response. Previously, a
   truncated partial was left as the final message.

3. Telegram edit_message comment alignment (telegram.py):
   Clarify that long flood waits return failure so streaming can fall
   back to a normal final send.
