feat(ui): a host's "Full metrics" heads its page, and a resource's anomalies are one line with a way to review them (#6797)

The host page's link to the full metrics sat in the Agent card, under the
anomaly card and the vitals strip, and was missed. It now heads the vitals
strip at the top of the page.

The anomaly card on the host, monitor, container and Traefik pages listed
every anomaly of the last 30 days with its review form, reviewed ones
included, and took over the top of the page. It is now one line: how many
wait for review, which are out of their normal now, and a Review button to
Alerts → Anomalies narrowed to that resource (?source=&resource=), where a
review returns. It is hidden when nothing waits and nothing is going on.
The callers fetch up to 100 rows so the count isn't capped at 10 or 20.
