fix: merge global + org-scoped token scopes in OrgResolver

Vendor's platform:admin scope comes from a global Logto role, which is
only present in the non-org-scoped token. OrgResolver now fetches both
the global token and the org-scoped token, merging their scopes. This
ensures vendor users see platform:admin and land on the vendor console.
