test(openai): use gpt-4o for image token counting (#38089)

Image token counting integration coverage is pinned back to `gpt-4o`,
whose usage metadata matches the local vision token estimator. A recent
model refresh moved these checks to `gpt-4.1-mini`, which reports
different live image token usage and broke the exact equality
assertions.
