runCodeMieSsoCliFlow function

Future<CodeMieSsoCredentials?> runCodeMieSsoCliFlow({ required String codeMieUrl, required void onStatus(String), Future<bool> openBrowserFn(String) = openBrowser, })

Runs the CodeMie SSO login: starts the callback server, opens (or prints) the organization's login URL, waits for the token, and decodes it into CodeMieSsoCredentials. Returns null on cancel/timeout/failure.
