Update URLs and enhance song output logging

- Changed `BaseUrl` and `AuthUrl` in `GlobalObjects.cs` to hardcoded "https://songify.rocks" for simplified configuration.
- Modified parameter name in `currentSongOutput` formatting in `SongFetcher.cs` for improved clarity.
- Added functionality to log the current song's URL to `url.txt` in `GlobalObjects.RootDirectory`.
