ci: build ISO from generated desktop dish via make all

- both ISO workflows run the new single 'make all' pipeline (they
  previously referenced the removed recipe-generator/ directory and
  nonexistent live kickstarts) and build from the generated
  desktop_43_standard_grub_gnome_guest-agents dish
- README: document the data-driven cooking pipeline (manifest +
  templates + make all), generated build products, and updated
  deploy/dish examples
