Enable kiosk functionality on client

Status Q1 2026:

This needs to be reworked into a user-story and could potantially serve as a test-case for using OpenGitOps and bootc technologies.

Create user functionality has been changed to generate a random password for the user instead of the static password previously set inline in the script.

This improves security concerns as a static password is no longer used for all devices deployed with this method.

If there is a need for logging into the device directly for some manual local admins tasks, this needs to be set manually some way. But as it is now all remotely automated, I cant imagine what use case there would be for this.. Maybe im wrong?
