Pull Request Overview

This PR updates the Google Sign-In implementation to properly handle ID tokens by storing them in the AccessToken object alongside access tokens. The changes ensure that the ID token received from Google Sign-In is preserved and made available through the AccessToken, even when access token retrieval fails.

• Modifies AccessToken creation to include ID token parameter
• Preserves ID token in error scenarios where access token retrieval fails
• Updates token handling to use multi-parameter AccessToken constructor

The code assumes a 4-parameter AccessToken constructor exists, but this may be a breaking change if the existing AccessToken class doesn't support this constructor signature. Consider verifying that the AccessToken class has been updated to support these parameters.

Suggested change

	setAccessToken(new AccessToken(accessToken, expiresIn, refreshToken, idToken));
	AccessToken token = new AccessToken(accessToken, expiresIn);
	// Set refreshToken and idToken if setters are available
	try {
	java.lang.reflect.Method setRefreshToken = token.getClass().getMethod("setRefreshToken", String.class);
	setRefreshToken.invoke(token, refreshToken);
	} catch (Exception e) {
	// Setter not available, ignore
	}
	try {
	java.lang.reflect.Method setIdToken = token.getClass().getMethod("setIdToken", String.class);
	setIdToken.invoke(token, idToken);
	} catch (Exception e) {
	// Setter not available, ignore
	}
	setAccessToken(token);
