CI's unit + coverage jobs failed with `FileNotFoundError: 'container'`: three
tests reached the real Apple CLI, which exists on a macOS dev host but not on
the Linux runner. They passed locally for that reason alone — and two of them
were quietly creating real Apple networks on the dev host as a side effect.
- `test_enumerate_active_is_empty_while_disabled` asserted the disabled-era
stub and called `enumerate_active()` unmocked. The backend launches bottles
again, so it now covers the real enumeration: slug parsing, exclusion of the
shared gateway/orchestrator singletons, and the CLI-failure path.
- The two orchestrator tests patched `orchestrator_service.container_mod`, but
`_run_orchestrator_container` reaches the CLI through `ensure_networks`,
which is imported from the gateway module and resolves `container_mod` in
*its* namespace. Patch the imported name instead.
Adds a test that the networks exist before the orchestrator runs — the
ordering the escaped call was hiding.
Verified by reproducing the CI environment locally (`PATH` without the
`container` binary): 3 failures before, 1818 passing after.

Re-enables the macos-container backend on the shared per-host orchestrator +
gateway, replacing the per-bottle companion container removed in #385. This is
the last backend in PRD 0070's roadmap.
Apple Container 1.0.0 forced three departures from the docker shape, each
verified against the live CLI (findings recorded in the networking spike):
- No `--ip`. The address is DHCP-assigned and knowable only once the container
runs, so the order inverts: gateway up -> run agent -> read its address ->
register. The identity token is minted by registration and therefore cannot
be in the agent's run-time env; it rides the proxy URL applied at
`container exec` time (bare `--env` names keep it off argv).
- No container DNS. The gateway can only be handed the control plane's IP, so
the orchestrator starts first and the gateway is pointed at its address.
- No `network connect`. Networks are fixed at run time, so the shared host-only
network is created up front; per-bottle networks would restart the gateway
on every launch and defeat the consolidation.
The agent runs with `--cap-drop CAP_NET_RAW`: Apple grants NET_RAW by default,
which would let an agent forge a neighbour's source address on the shared
segment. NET_ADMIN is already absent, so this closes the source-address half of
PRD 0070's attribution invariant.
Verified end-to-end on real Apple Container 1.0.0: both images build, the
control plane comes up healthy, the gateway reaches it by IP, and a registered
agent gets 200 for a host in its routes and 403 for one outside them. Bring-up
is idempotent — a second launch does not churn the singletons.
