Refactor screen rotation setup and GTK theme configuration in first-boot process

Browse Source 
Update the one-shot script to set screen rotation using kanshi based on kernel command line parameters, replacing the previous wlr-randr method. The script now writes the configuration to ~/.config/kanshi/config and sets the GTK dark theme (PiXnoir or Adwaita-dark) at first login. Additionally, enhance documentation to reflect these changes and clarify the role of the new script in the first-boot process.
