fix(spectral_editor): Resolve variable name conflict in playAudio

Fixed 'Identifier source has already been declared' error at line 935.

Bug: Function parameter 'source' (string: 'procedural' or 'original')
     conflicted with local AudioBufferSourceNode variable.

Fix: Renamed local variable to 'bufferSource' for clarity.
