fix: use explicit azureOpenAiDefaultApiVersion fallback when apiVersion is empty

hannesrudolph · hannesrudolph · commit 276cb036dec9 · 2026-02-09T10:22:59.000-07:00
Addresses review feedback: the UI placeholder shows '2025-04-01-preview' via
azureOpenAiDefaultApiVersion, so the handler should use the same constant as
fallback instead of silently deferring to the SDK's internal default.
