feat(docker): the Docker page leads with a verdict, lists services and containers as filterable tables, and each service has its own page with logs across its tasks (#5298–#5302)

- #5298 "Docker overview: verdict line; only the problem tiles that aren't zero"
- #5299 "Docker overview: swarm services as a filterable, sortable table with a Stack column"
- #5300 "Docker overview: failures listed once, each with a link to the failed task's logs"
- #5301 "Docker overview: standalone containers in one table with a Host column"
- #5302 "Service page: replicas, image, task history, resource history and logs across all its tasks"

overview.py holds the rows, filters and sort as plain functions. The filter
bar sits outside the polled fragment and the URL keeps its state. A service's
page reads every task container Steward still holds anything for, the live
ones and removed ones known by their events, so a failed task's logs are
reachable after Docker has removed it.
