fix(pyright): resolve type errors introduced by lifecycle refactor

- Remove unused INFRA_IMAGE import from test_orchestrator_lifecycle
- Update integration test to use new single-container OrchestratorService
  API (infra_name/image replaces orchestrator_name/gateway_name/gateway_image)
- Move type: ignore to the lambda line in gateway_init SIGHUP handler
- Break two long lines in test_orchestrator_lifecycle
