🐛 Patch Changes

• cf98f70: Fix OpenAI subscription model discovery so newer Codex CLI models (e.g. gpt-5.5) appear. The hardcoded client_version=0.99.0 query param made https://chatgpt.com/backend-api/codex/models silently return only the older subset; bump it to 0.128.0 and lift Codex/Copilot client identifiers into a shared constants file so future bumps are a one-line change.
• a7a9c3b: Fix fallback success rows recording the primary route's auth_type instead of the fallback's, which caused cost_usd to be miscomputed on mixed-auth chains (subscription fallbacks were charged, api_key fallbacks were stored as $0).
• be679c4: Strip Codex-unsupported parameters on the OpenAI subscription proxy path. Requests forwarded to chatgpt.com/backend-api/codex/responses now drop temperature, top_p, max_output_tokens, metadata, safety_identifier, prompt_cache_retention, and truncation before the upstream call, and force store: false. Previously these fields propagated through and Codex returned 400 unsupported_parameter, breaking OpenAI-SDK clients that set sampling defaults. Closes #1791.
