feat: verify AI Gateway provider UX and attribution headers (#950 )

Closes #950 - promote Vercel AI Gateway near the top of the provider picker - add dedicated AI Gateway model flow with Vercel API-key deep link and live pricing - use curated AI Gateway catalog refresh with free Moonshot auto-promotion - apply AI Gateway attribution headers on runtime clients - add targeted QA tests for provider UX and attribution headers
