Refactor loop condition and canvas download logic

Updated the loop condition in `IOManager.cs` to clarify intent when handling locked files. Refactored canvas downloading in `SongFetcher.cs` to ensure `GlobalObjects.Canvas` is cleared after download, improving code clarity and maintainability for both `PauseText` and `ClearAll` options.
