The grace-period branch assigned the recursive get_data result (a
finished LiteLLM_VerificationTokenView) back into the variable that the
combined-view dict normalization then subscripts, raising TypeError on
every request made with a rotated key inside its grace window; auth
surfaced that as a 401. Return the recursive result directly instead.
Regression test drives the full get_data flow: old hash misses the view,
deprecated table resolves to the active token, and the call must return
the view object
