isAuthenticationError(error: AuthError): boolean
Determines if an error is related to authentication failure.
Parameters
- error: AuthError
  The AuthError instance to evaluate.
Returns boolean
true if the error indicates invalid credentials, expired CSRF,
missing session, or insufficient permissions, otherwise false.

  redirectToLoginPage();
}

@public
```
