🔧 Fix Cloudflare build issues and restore Docker support

✅ Cloudflare Pages Fixes:
- Fix IPTV page Suspense boundary issue for static generation
- Resolve ESLint warnings (unused imports, console statements)
- Remove dependency on useSearchParams for static builds
- Improve error handling without console.error

🐳 Docker Support Restored:
- Add complete Docker configuration (Dockerfile, docker-compose.yml)
- Support both basic (localstorage) and Redis deployment modes
- Multi-platform builds (amd64/arm64) via GitHub Actions
- Production-ready with health checks and proper security

📚 Documentation Updates:
- Comprehensive deployment guide for all platforms
- Docker quick start and production examples
- Environment variable documentation
- Updated README with multi-platform support

🎯 Key Improvements:
- Multiple deployment options: Cloudflare + Docker + Vercel
- Better error boundaries and loading states
- Optimized build processes for each platform
- Enhanced developer experience

This fixes the Cloudflare Pages deployment while providing
Docker as an alternative self-hosting option.
