refactor(orchestrator): introduce the Orchestrator service ABC (docker impl)

Mirror the Gateway work for the control plane. Add the backend-neutral
`Orchestrator` service ABC in orchestrator/lifecycle.py — build the image/rootfs,
`ensure_running` (start + health-gate), `is_running`/`is_healthy`/`stop`,
`url()` (host-facing) vs `gateway_url()` (what the gateway resolves against),
and a concrete `mint_gateway_token()` (the orchestrator holds the signing key,
so it issues the gateway's token — #469).

`DockerOrchestrator` (backend/docker/orchestrator.py) is the first impl,
extracted out of `DockerInfraService`: the control-plane container run, the
`--internal` control network, the source-hash recreate gate, health polling,
and the orchestrator constants (name/label/network/image/dockerfile/hash-label).
`DockerInfraService` now composes `orchestrator()` + `gateway()` — each builds
its own image via `ensure_built`, the orchestrator comes up first, then the
gateway is connected with the orchestrator-minted token. Its `url`/`is_healthy`
delegate to the orchestrator service.

Split the container-lifecycle tests into test_docker_orchestrator; test_docker_infra
now covers the composition. macOS + firecracker follow.

"""Unit: orchestrator + gateway container lifecycle (PRD 0070 plane split).
"""Unit: DockerInfraService composes the orchestrator + gateway services.
`DockerInfraService` brings up two containers the lean orchestrator on the
`--internal` control network + host loopback, and the dual-homed gateway. These
tests isolate the orchestrator-container logic by mocking `gateway` (the
gateway runs via `DockerGateway`, exercised in its own test)."""
`DockerInfraService` no longer owns the container lifecycles it composes the
`DockerOrchestrator` (control plane) and `DockerGateway` (data plane) services,
each tested in its own module. These tests isolate the *composition*: both are
built, the orchestrator comes up first, then the gateway is connected to it with
a freshly minted token."""
