fix(codex/azure): remove conflicting requires_openai_auth from Azure preset

[wh9204]

Problem

The Azure OpenAI preset in codexProviderPresets.ts ships with both:

• env_key = "OPENAI_API_KEY" (env-variable auth)
• requires_openai_auth = true (OpenAI OAuth login)

These two fields are mutually exclusive per the Codex config reference:

Do not combine with env_key, experimental_bearer_token, or requires_openai_auth.

When a user follows the README and sets OPENAI_API_KEY, Codex still errors out with Missing environment variable: OPENAI_API_KEY. — because requires_openai_auth = true makes Codex demand an OpenAI OAuth login flow and ignore the env-key auth path.

Fix

Remove the conflicting requires_openai_auth = true line from the Azure preset. Azure OpenAI authenticates via API key (env_key), not OpenAI OAuth.

Verification

• Generated config now matches the Microsoft Learn canonical Azure setup.
• Setting OPENAI_API_KEY env var and running codex connects to Azure OpenAI successfully (reproduced on Windows 10, Codex v0.130.0, model gpt-5.5).

Scope

Intentionally minimal — only the Azure preset is touched. Some third-party presets generated by generateThirdPartyConfig() may have the same conflict, but each needs case-by-case verification and is out of scope for this fix.

Related: #1309 (broader Azure compatibility PR, but does not modify this file).

Review

LGTM. No blocking issues.

The fix is correctly scoped. Per the Codex config reference, env_key and requires_openai_auth are mutually exclusive, and the Azure preset was the only entry in src/config/codexProviderPresets.ts that set both. Removing requires_openai_auth = true at line 113 resolves the auth conflict without affecting any other preset:

• Other third-party presets generated by generateThirdPartyConfig() (line 62) emit requires_openai_auth = true but do not set env_key, so they are not in the same conflicting state. The author's decision to leave them alone is correct.
• E-FlowCode (line 419) and PIPELLM (line 458) follow the same requires_openai_auth-without-env_key pattern — also out of scope.
• The auth path is unchanged: auth.json still carries OPENAI_API_KEY via generateThirdPartyAuth(""), which Codex reads through the env_key reference in the TOML.

The generated TOML now matches the Microsoft Learn canonical Azure setup cited in the PR description.

Tasks

• Read PR diff
• Inspect codexProviderPresets.ts context
• Confirm no other presets have the same env_key + requires_openai_auth conflict
• Post review
  • branch fix/codex-azure-remove-requires-openai-auth
