fix(tauri): serialize startup navigation

Let the native CLI manager exclusively navigate the loading window once the managed server is ready. This prevents the loading renderer from racing the native client-state navigation and replacing a document after its access token has been rotated.

Error and status reporting remain in the loading renderer, while native navigation continues to preserve authentication redirects. Validated with UI typecheck/build and packaged-resource smoke checks.
