Add comprehensive service integrations and games to BlackRoad OS

This massive update transforms BlackRoad OS into a complete virtual operating
system with modern cloud integrations and retro-styled games.

New API Integrations:
- DigitalOcean: Droplet management, spaces, regions, and account info
- GitHub: Repo browsing, commits, PRs, issues, code search, notifications
- Hugging Face: Model browser, inference API, datasets, spaces, trending
- VS Code: Monaco editor integration with file tree and syntax highlighting

Games (SimCity/Sims style):
- Road City: City builder with zones, utilities, services, and resources
- Road Life: Life simulator with characters, needs, skills, and jobs
- RoadCraft: Voxel world builder with block placement

Enhanced Features:
- RoadView Browser: Web proxy with bookmarks, history, tabs, and search
- Device Manager: SSH connections, remote command execution, deployments
- Unified Dashboard: Comprehensive overview of all services and stats

Backend Enhancements:
- 7 new API routers with 100+ endpoints
- Enhanced device management with SSH and deployment capabilities
- Service health monitoring and activity tracking
- Support for DigitalOcean, GitHub, and Hugging Face tokens

Configuration:
- Added environment variables for new API tokens
- All integrations properly registered in main.py
- Comprehensive error handling and validation

This brings the total to 15+ integrated services creating a complete
retro-styled virtual operating system with AI, cloud, games, and dev tools.
