This only fixes base64url decoding for ID tokens. getAccessTokenClaims() still uses raw base64_decode() on the JWT payload, so valid access tokens that need URL-safe normalization or padding will still fail. Please extract this decode logic into a shared helper and reuse it for both token-claim paths.
