feat: Migrate from ai/rsc to ai/ui

[ngoiyaeric]

Summary

Migrate from the deprecated AI SDK ai/rsc package to the new ai/ui package for Next.js App Router integration.

Changes

• Replace createAI provider with useChat hook from ai/ui
• Add new /api/chat route handler that supports both JSON and formData formats
• Implement full feature parity with previous implementation:
  • Resolution search (image upload for map analysis)
  • Related queries via querySuggestor
  • Follow-up panel
  • Drawing features passed via extraBody
• Update chat.tsx and chat-panel.tsx to use the new useChat hook
• Simplify suggest.ts to use standard promise-based API

Testing

The migration has been tested locally with the following features:

• Text input and streaming responses
• FAQ handling (planet computer, QCX-Terra)
• Rich tool integrations (search, retrieve, video search, geospatial)
