* fix(openai): remove chatgpt-responses transport override from gpt-5.3-codex catalog entry
The static catalog entry for gpt-5.3-codex hardcoded
api: "openai-chatgpt-responses" and baseUrl: "https://chatgpt.com/backend-api",
forcing all users through the ChatGPT backend — which requires OAuth, not
a standard API key. This broke gpt-5.3-codex for every API-key user after
v2026.6.1.
Remove the transport overrides so the model inherits the provider defaults
(openai-responses + api.openai.com/v1), restoring v2026.5.18 behavior.
OAuth/Codex users are unaffected — dynamic model resolution in
shouldResolveDynamicModelThroughCodex handles the ChatGPT routing based
on provider config, not the static catalog entry.
* ci: retrigger opengrep scan (transient install failure)
