/audio/{id} and /audio/version/{id} hardcoded media_type="audio/wav" on
the FileResponse. That was a no-op when every generation came out of
TTS (everything on disk was a .wav anyway), but imported audio keeps
its source format — .mp3 / .m4a / .ogg — and the WaveSurfer MediaElement
backend uses an <audio> tag that checks Content-Type before letting the
clip play, so an MP3 announced as audio/wav silently failed to load.
Both endpoints now derive the type via mimetypes.guess_type and fall
back to audio/wav for unknown suffixes. Download filenames also keep
the real extension instead of always saying ".wav".
