The `DockerGateway` container-lifecycle impl now lives in `backend/docker/gateway.py` (the shape backend gateway classes will share); `orchestrator/gateway.py` keeps only the backend-neutral pieces (the `Gateway` ABC, constants, `rotate_gateway_ca`). Delete the standalone-gateway path it was the only consumer of. `--gateway` on `python -m bot_bottle.orchestrator` was invoked nowhere — the production docker flow runs the gateway data plane inside the combined `bot-bottle-infra` container via `OrchestratorService`, never this class. Removing it takes with it `Orchestrator.ensure_gateway()` and the `gateway` ctor arg; `gateway_status()` becomes a stub reporting `configured: false` so the documented `GET /gateway` control-plane route keeps its contract. Fix a latent bug the move surfaced: `launch.py` read the shared gateway CA via `docker exec bot-bottle-orch-gateway`, a container the consolidated flow never creates — so the agent CA install was reaching a nonexistent name. Read it from `bot-bottle-infra` (INFRA_NAME) instead. Repoint the affected tests to the new module; drop the unit test + fake that covered the deleted standalone wiring.
