feat: Migrate from Socket.IO to Server-Sent Events (SSE)

- Replace Socket.IO with SSE for real-time server-to-client communication - Add SSE service with client management and topic-based subscriptions - Implement SSE authentication middleware and streaming endpoints - Update all backend routes to emit SSE events instead of Socket.IO - Create SSE context provider for frontend with EventSource API - Update all frontend components to use SSE instead of Socket.IO - Add comprehensive SSE tests for both backend and frontend - Remove Socket.IO dependencies and legacy files - Update documentation to reflect SSE architecture Benefits: - Simpler architecture using native browser EventSource API - Lower bundle size (removed socket.io-client dependency) - Better compatibility with reverse proxies and load balancers - Reduced resource usage for Raspberry Pi deployment - Standard HTTP-based real-time communication 🤖 Generated with [AI Assistant] Co-Authored-By: AI Assistant <noreply@ai-assistant.com>
