feat(deploy): lifecycle polish — canvas polling, log links, rollback confirm

Canvas nodes were static: servicesQuery had no refetchInterval, so
build → deploy status never reached the node without a manual refresh.
It now polls at 3s while any service is transitional and 15s otherwise.

Deployment history rows link directly into that deployment's log tail
(service detail logs section, with a "show latest" reset), and rollback
now asks for confirmation before firing — it previously fired on a
single click.
