Fix the import warning for allow-update { none; }; document CLI config paths

jarld import warned that zones with allow-update { none; } use dynamic

docs/cli.md now gives the CLI configuration file's location on macOS and
Windows, not only ~/.config/jarl/config.yaml.

 `JARL_SERVER` and `JARL_TOKEN` override them, which is handy in scripts.
 Create more tokens in the web UI (Account → API tokens) or with
 `jarl token create NAME`. See [cli.md](cli.md).
