🤖 fix: switch runtimeFileEditing tests to codex-mini for faster response

The file editing integration tests were flaky due to timeout waiting for
Anthropic Claude Haiku API responses (15s timeout). Switching to OpenAI's
gpt-5.1-codex-mini model which is faster and more reliable for these
simple file editing tasks.

Also fixed the helper constant name from GPT_5_MINI_MODEL to CODEX_MINI_MODEL
with the correct model identifier (gpt-5.1-codex-mini).
