Refactor CDN and run_once handling

- Move run_once include from main.yml to 01_core.yml in desk-gnome-caffeine and desk-ssh
- Introduce sys-svc-cdn/01_core.yml to handle shared/vendor dirs once and role dirs per run
- Replace cdn.* with cdn_paths_all.* across inj roles
- Split cdn_dirs into cdn_dirs_role and CDN_DIRS_GLOBAL
- Ensure cdn_urls uses cdn_paths_all
