Fix: Prevent AuthManager state pollution on connection verification (#348)

* Fix: Prevent AuthManager state pollution on connection verification

Modified `ConnectViewModel.connect()` to construct a temporary OkHttpClient and Retrofit builder, isolated from the global `ApiClient` state. The connection verification is executed using this temporary service. Only upon a successful HTTP response does the system persist the configured `host`, `port`, and `token` to the global `AuthManager` and triggers an `ApiClient.rebuild()`. This resolves the issue where a failed connection attempt would overwrite active and verified profiles. Extracted `createTempService` factory to `ApiClient` for robustness and clean tests.

Fixes #260
