Remove symbols with no remaining consumer: - `gateway_name` property on Docker/MacosInfraService — nothing uses it; the launch flow reads `gateway().name` off the Gateway service. (+ its docker test.) - firecracker `infra_vm` EGRESS_PORT / SUPERVISE_PORT / GIT_HTTP_PORT — dead duplicates; launch.py uses supervisor.types / docker.egress / a local const. - macOS `INFRA_DB_VOLUME` back-compat alias — unused since the DB-volume test moved to `ORCHESTRATOR_DB_VOLUME`. - docker `infra.py`: the unused `ORCHESTRATOR_SOURCE_HASH_LABEL` import and the `__all__` re-exports of the orchestrator constants (consumers import them from `docker.orchestrator`, not `docker.infra`). - macOS `infra.py`: the unused `GatewayError` import + re-export.
