fix: check audio inputs before image inputs in schema extraction

isImageInput() has permissive description heuristics (e.g. "data uri")
that false-positive on audio properties like audio_url whose description
mentions "base64 data URI". Reorder the checks so isAudioInput() — which
uses specific name patterns — runs first.
