Full Hands-Off Installation Routine

As a user, I'd like to preconfigure players (rPi 5) with a custom installation script. I can define a central studio instance via URL or IP and preconfigure a Wi-Fi to connect to. I then take the player and just put it at the specific site, where it starts up and connects to the central studio instance.

There is no interaction needed for the setup onsite, since everything is already configured nicely.

As a safety measure, the script should shut down root access and every other way of tampering with the device (software-wise)
