fix: streaming service uses :latest image (fixes voice drift on port 8023)

The :streaming tag was the pre-v5 image with non_streaming_mode=False,
causing the same voice drift bug as voiceclone had before v5. The streaming
service runs identical code (run_server.py -> openai_server.py) so it uses
:latest which has the non_streaming_mode=True fix. The QWEN_TTS_* env vars
were unused since the command overrides them; removed for clarity.
