Implement P5: Connect Tray to REST/SSE

- Create API client for /api/v1 endpoints with SSE support
- Add adapter pattern to bridge API client with ServerInterface
- Update tray to communicate via HTTP API instead of direct imports
- Add 'Open Web Control Panel' menu item
- Remove direct core package dependencies from tray
- Achieve clean separation: tray ↔ HTTP API ↔ core server
- Maintain real-time updates and full server management functionality
