fix(cline): use valid modelType/model format for Cline provider models (#11099) (#11132)

Cherry-picked the value commit (ac09b6b5) onto the current release tip, dropping the stale base-red sync commits that no longer apply. Focused test cline-model-format-11099 2/2 green; check:provider-consistency OK (267/348/0). Fixes #11099 — the zai→z-ai namespace typo. Thank you @rqzbeh!
