[FEATURE] Add a preview screen before the song displaying the song name and the user who added it.

Is your feature request related to a problem? Please describe.
Currently, a small popup appears in the corner showing the song name and the user who added it. While this provides some information, it is easy to miss, especially in a karaoke setting where users might not be paying close attention to small on-screen elements. It would be clearer and more engaging to dedicate a full-screen preview before the song starts.

Describe the solution you'd like
I would like to add a preview screen that appears before each song starts. This screen should display:
1. The name of the song.
2. The username of the person who added the song to the queue.

The preview screen would remain visible for a few seconds before the song begins.
