ci(integration-macos): dump infra logs on failure before teardown

A control-plane failure (e.g. the orchestrator becoming unreachable at
bottle registration) is undiagnosable from CI as-is: the `if: always()`
teardown runs `MacosInfraService().stop()`, which deletes the
orchestrator and gateway containers — and their logs — on every run.

Add an `if: failure()` step that dumps `container ls`/`network ls`, plus
`inspect` and `logs` for `bot-bottle-mac-orchestrator` and
`bot-bottle-mac-infra`, ordered before the teardown so the evidence is
captured while the containers still exist. Best-effort (never fails the
job; tolerates an already-removed container).
