[Feature Request]: work on a more minimalistic and Modern UI + improvements

[neox1de]

Hello there👋

I have a few recommendations and ideas for improving the front-end.

1, The current front-end is functional, but a more modern and minimalistic design could greatly increase the speed and make the app easier to use.
2. It would be incredibly useful to have a button or option on the front-end to add new music to the radio.
3. Replacing the current volume buttons (1 to 5) with a slider would provide more precise control and align with modern UX standards. Sliders are more intuitive and widely used in media players, so this change could improve usability.
4. Adding the ability to replay a specific track would be a great feature for users who want to listen to a song again without waiting for it to cycle through the playlist.
5. Dockerizing the project would make it much easier to set up and deploy across different environments. A Dockerfile and optionally a docker-compose.yml file could simplify installation, improve consistency, and make the project more accessible to users who prefer containerized workflows
