fix(openai-adapters): suppress org/project headers that break under Turkish locales

[edenbuilds]

Summary

• Under Turkish locales, the OpenAI SDK's OpenAI-Organization / OpenAI-Project headers lowercase to invalid HTTP tokens (openaı-organization) and crash requests.
• Explicitly set organization/project to null and null out those headers with ASCII-safe lowercase keys so OPENAI_ORG_ID / OPENAI_PROJECT_ID from the environment cannot inject the PascalCase headers.
• Applied in both OpenAIApi and AzureApi client construction.

Fixes #12568

Test plan

• Regression test asserts OpenAI-Organization.toLocaleLowerCase(tr-TR) produces the invalid token, and that our client does not pick up org/project from env
• A/B: without the fix, openai.organization leaks OPENAI_ORG_ID; with the fix it stays null
• vitest --run src/test/main.test.ts passes

CI note: the two failing checks look unrelated to this OpenAI-adapters header change:

• e2e/.../PromptFile.test.js (yaml) — ReadError: The server aborted pending request (infra flake; the non-yaml PromptFile e2e passed)
• jetbrains-tests — JetBrains plugin suite; this PR only touches packages/openai-adapters

Happy to re-run those checks if a maintainer can kick them, or push an empty commit if that helps.

CI update after retrigger: PromptFile yaml is green now. Remaining failure is `jetbrains-tests` → IntelliJ `Autocomplete.testAutocomplete()` assertion (unrelated to this openai-adapters Turkish-locale header change). Happy to ignore/re-run if maintainers prefer.

Heads-up on the red check: jetbrains-tests here is failing on Autocomplete > testAutocomplete() (Autocomplete.kt:42), which is the IntelliJ integration suite and doesn't touch this change.

It looks like a broken baseline rather than something this PR introduced — the three most recent failing PR Checks runs on unrelated branches all fail the same job:

branch	failing jobs
fix-autocomplete-prune-length-min-response-tokens	jetbrains-tests, require-all-checks-to-pass
snyk-fix-ec3df2206…	jetbrains-tests, packages-checks (openai-adapters), all e2e, …
snyk-fix-cfe49b462…	core-checks, jetbrains-tests, packages-checks (openai-adapters), all e2e, …

The first is the same two-job failure as this PR. require-all-checks-to-pass is just the aggregate gate downstream of it.

packages-checks (openai-adapters) — the job that actually covers this change — is green here.

Happy to rebase once the JetBrains suite is healthy on main if that's the simplest way to get a clean run.
