Fix service manager examples to use production-ready API

- Updated simple_service.rs to use start(config) instead of create() + start(name)
- Updated service_spaghetti.rs to use the same unified API
- Fixed factory function calls to use create_service_manager() without parameters
- All examples now compile and work with the production-ready synchronous API
- Maintains backward compatibility while providing cleaner interface
