When /api/generate returns 403 (tier limit), the dashboard silently fails. User has no idea why generation stopped.
Current behavior: Button stops, no feedback.
Expected: Show a branded modal/popup: 'You've reached your free tier limit (10 articles). Upgrade to Pro for up to 30 articles per brand.'
This is an upsell opportunity — make it feel helpful, not pushy. Include upgrade CTA button.
Depends on: #3 (Stripe billing)
