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)
CI / lint (push) Successful in 2s
CI / integration (push) Failing after 1m4s
CI / unit (push) Failing after 1m28s
CI / publish (push) Skipped

- #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.

"""The Docker page's two tables, as plain rows (#5299, #5301): one row per
swarm service and one per standalone container, with the search, stack, host
and status filters and the column sort the page offers. Model-free, so it is
unit-tested without a database; routes.rows() feeds it.
A stack is how the operator thinks of a group of services. Swarm names a
stack's services "<stack>_<service>", so a service's stack is the part of its
name before the first "_"; a standalone container's is its compose project.
Stacks filter the list rather than section it, as host groups do on Hosts.
