Type Alias AuthRefreshCallback 

pub type AuthRefreshCallback = Arc<dyn Fn() -> Pin<Box<dyn Future<Output = Result<AuthProvider, KalamLinkError>> + Send>> + Send + Sync>;

Async callback that resolves fresh AuthProvider credentials.

Called by the executor when a query requires a login exchange or returns TOKEN_EXPIRED. Implementations should obtain a fresh JWT (e.g. via login or dynamic auth provider) and return it.
