feat: Update FAISS index with all services on startup

- Add FAISS index update logic in lifespan function after initialization
- Iterate through all registered services and call add_or_update_service
- Include proper error handling for individual service updates
- Track service enabled/disabled state in the index
- Add comprehensive logging for the update process

Fixes #54
