Fix audio file deletion: Correct path resolution for file deletion

Critical bug fix for audio deletion:

Issue:
- deleteSelectedAudio() was passing category and filename to deleteAudio()
- deleteAudio() expects full file path as first parameter
- This caused deletion attempts on directory paths like 'C:\Users\drew\webGame\background'
- Result: ENOENT errors trying to delete directories instead of files

Fix:
- Look up full audio file path from storage before calling deleteAudio()
- Handle both string and object audio storage formats
- Pass correct audioPath parameter to deleteAudio(audioPath, category)
- Enhanced removeAudioFromStorage() to handle both storage formats properly

Changes:
- deleteSelectedAudio(): Find full path from storage before deletion
- removeAudioFromStorage(): Support both string paths and object formats
- Proper error handling when audio file not found in storage
- Maintains backward compatibility with different storage formats

Now audio deletion works correctly:
 Finds correct file paths from storage
 Deletes actual audio files from disk
 Removes storage references properly
 No more ENOENT directory deletion errors
