Add secure OpenAI prompt app

[setnilson]

Summary

App Builder

Add a Datadog App that lets users submit a prompt to OpenAI while keeping the API credential in a Datadog HTTP connection.

Changes

• Scaffold the apps/openai-prompt workspace app with DRUIDS styling and Datadog embedding providers.
• Add a backend function that validates prompts and calls the OpenAI Responses API through Action Catalog.
• Add loading, error, character-count, and response states to the prompt form.
• Document the required static Datadog HTTP connection configuration.
• Regenerate the root workspace lockfile with React aligned to 18.3.1.

Testing

• npm ci --ignore-scripts
• npm run typecheck -w apps/openai-prompt
• npm run lint -w apps/openai-prompt
• env -u DATADOG_SITE -u DD_SITE npm run build -w apps/openai-prompt
• Browser preview validated at 1280x720, including prompt entry, character count, and submit-button state.
