fix(admin): prevent combobox reset after save by stopping unnecessary Ollama refetch

The Ollama model useEffect hooks were triggering on every config prop
change (including after revalidatePath), causing a model list refetch
that reset the combobox selection. Limited dependencies to provider
state only so fetch only runs on mount and provider switch.
