Adds subscription status tracking and display functionality to the chat interface. The key components are:

• A new SubscriptionStatus Vue component that displays:
  • Subscription status (subscribed/not subscribed)
  • Weekly chat usage and limits for free tier
  • Link to subscription documentation
• Registration flow to create conversation threads with subscription data
• Integration with the existing chat interface
