After Recent Updates, File -> Load from Computer for .wav files fails (fix included)

I can drag-and-drop successfully, but File -> Load from Computer has no effect - no messages or exceptions printed to the console either.

Google Chrome 135.0.7049.52 on Linux x64

The reason is that in engine.js line 151 (in the LoadFile() function), you check if the MIME type of the audio file is audio/wave, but the correct MIME type for .wav files is audio/wav. Changing that line fixes the problem.
