When Cedar is configured with a primaryUpstreamProvider (auto-derived from the sole upstream), RFC 8693 delegated tokens have no UpstreamTokens entry and resolveClaims failed closed before policy evaluation. Fall back to the request token claims so delegation remains usable, mirroring the existing opaque-token fallback. Fixes stacklok#6424 Signed-off-by: lorenzozanee <wyz0707@proton.me>

Summary
Delegated tokens minted via RFC 8693 have no upstream session and were denied by Cedar when
primaryUpstreamProvideris set, even for permissive policies. Fall back to the request token's claims in that case, mirroring the existing opaque-token handling, so delegation can be evaluated.Fixes #6424

Yes. Delegated flows now authorize correctly when Cedar uses a primary upstream provider; otherwise behavior is unchanged.
