refactor(docker): rename OrchestratorService -> DockerInfraService, move to backend/docker
OrchestratorService wasn't the orchestrator — it's the host-side lifecycle of
the docker infra *container* (the one that runs the Orchestrator). It read as
"the orchestrator as a service" and lived in orchestrator/lifecycle.py, while
its siblings (macOS MacosInfraService, Firecracker infra_vm) live under their
backend package. Rename it DockerInfraService and move it to
backend/docker/infra.py alongside the docker backend, with its docker-only
constants (INFRA_*/ORCHESTRATOR_* image + container names, daemon list, mount
paths).

orchestrator/lifecycle.py keeps only the backend-neutral pieces the other infra
services share — DEFAULT_PORT, DEFAULT_STARTUP_TIMEOUT_SECONDS,
OrchestratorStartError, source_hash — which macOS / firecracker / client still
import from there. backend/docker/infra.py imports those (backend -> orchestrator
is an allowed direction). Renamed the unit test to test_docker_infra.py.

Full unit suite green (2243).

"""Rotate the shared gateway's mitmproxy CA (issue #450).
python -m bot_bottle.orchestrator.rotate_ca
A deliberate CA rollover has two halves: drop the *persisted* CA so a fresh one
is minted, and drop the *running* gateway so its mitmproxy (which holds the old
CA in memory) is replaced. This one-shot command does both:
1. Delete the persisted CA under the host gateway-CA dir — the next gateway
start generates a new one (mitmproxy reuses an existing CA, generates only
when absent).
2. Force-remove the infra / standalone-gateway containers so the stale
in-memory CA is gone; the next bottle launch's idempotent `ensure_running`
brings the gateway back up and mints the fresh CA.
It does NOT re-provision the new CA into already-running bottles — those must be
re-attached so they install the new trust anchor. Rotation is thus an explicit,
operator-driven action with a brief egress interruption, not an automatic one.
