Add a simple chat UI to the dashboard for quickly testing AI models from
connected providers. Features include:
- Model picker from all connected providers
- Streaming chat responses
- Image attachment support
- Session history with localStorage persistence
- Responsive design with dark theme
Note: Removed build.sh from original PR as it contained syntax errors and
was unrelated to the chat UI feature.
