reconcile_running_bottles() gathered the gateway attach-resources (a read of
the per-host singleton gateway's CA) *before* enumerating running bottles. On
a cold-boot bring-up of a NON-default gateway instance with no host bottles —
e.g. an isolated integration test's `-itest-` gateway — that read targeted the
default `bot-bottle-orch-gateway`, which doesn't exist for that instance, so
setUpClass died with "No such container: bot-bottle-orch-gateway" (seen on the
0081 PR's integration-docker job).
Enumerate running bottles first and return early when there are none: the
reconcile is a no-op with nothing to reattach, so the CA read is both wasted
and wrong for a non-default instance. Production (default names, real bottles)
is unchanged. Adds unit coverage for the three reconcile paths.
