Replace default model used in server-v3 api spec examples

[pirate]

why

Stainless generated clients had custom code changes that shouldn't have been custom code, they should've bene updated in the api spec. This fixes the root cause by replacing those, and then I'll have a follow-up PR for the python sdk to remove those custom code changes.

Summary by cubic

Updated v3 API examples to use OpenAI openai/gpt-5.4-mini, replacing previous defaults across the OpenAPI spec, core types, and stainless.yml. This aligns examples with our base URL and API key docs and avoids custom patches in Stainless-generated clients; no behavior changes.
