Use the Responses API for issue label suggestions (#60897)

## What changed

Replace the issue labeler's Codex action with a Python script that calls the Responses API with tools disabled and a strict JSON schema. Preserve the label catalog while validating one issue type, an optional product, and known area labels before applying them.

Retry transient API failures and timeouts, honor `Retry-After`, and reject redirects. Pass validated labels directly to `gh issue edit`, surface label application failures, and allow trigger-label cleanup after suggestion failures.
