Note

Low Risk
Test-only changes that make inputs deterministic; no production logic or security-sensitive code is modified.

Overview
Removes per-test random UUID suffixes from the user prompt content in the include_raw_response and include_raw_usage E2E suites, switching from format!(...) to fixed strings across chat-completions, responses, best-of-n, mixture-of-n, and DICL cases.

This makes the request payloads deterministic (and more compatible with proxying/caching behavior) without changing the assertions around raw response/usage inclusion.
