WhatsApp Cloud API was rejecting audio forwards with Error 131053 because
audio/opus MIME type is unsupported. WhatsApp expects audio/ogg; codecs=opus
for .ogg files.
When receiving audio from WhatsApp, the file may be served with audio/opus
content-type header. This fix detects audio/opus + .ogg extension and corrects
it to audio/ogg; codecs=opus before storing in ActiveStorage.
Note: ActiveStorage's Marcel gem may still override this during analysis.
This is a known limitation that needs architectural discussion.
