feat(nlq): add modelId to OpenAI NLQ configuration (#27789)

* feat(nlq): add modelId to OpenAI NLQ configuration

Mirrors the bedrock provider, which already exposes a modelId for query
transformation alongside its embeddingModelId. The OpenAI provider only
had embeddingModelId, leaving the chat-completions model hardcoded in
the client. Adding modelId here lets operators pick the chat model
(e.g. gpt-4o-mini, gpt-4o) per deployment without code changes.

* Update generated TypeScript types
