feat: add GPT-5.4 Codex fast mode models (codex, spark variants)

Browse source 
Adds three new model entries to the OpenAI Codex provider:
- gpt-5.4-codex: Full GPT-5.4 optimized for agentic coding (1M context)
- gpt-5.4-codex-spark: Fast, text-only GPT-5.4 variant (128k context, 8k output)
- gpt-5.4-mini-codex-spark: Fast, text-only GPT-5.4 Mini variant (128k context, 8k output)

Follows the same pattern as existing gpt-5.3-codex and gpt-5.3-codex-spark models.

Closes #12112
