Subject: [PATCH] refactor(AuthClient): Enhance AuthClient with lazy
 initialization and connection error handling

- Replaced immediate connection start with lazy initialization via Lazy<Task<bool>>.
- Added IsConnected and ConnectionError properties to track connection status and errors.
- Introduced TryStartAsync method to safely attempt connection startup without throwing exceptions.
