Remove deprecated one-shot scripts and update first-boot configuration for improved provisioning</message>

<message>Delete obsolete one-shot scripts for setting screen rotation and wallpaper, as well as related Python and shell scripts. Update the first-boot configuration to streamline the provisioning process by removing references to these scripts. This cleanup enhances maintainability and focuses on the essential steps required for the first boot experience, ensuring a more efficient setup for users.
