Make queued, running, warning, and failed run states more visible at the
top of the dashboard with contextual status summaries and highlighted
summary metrics.
Also show an all-clear message when configured hosts have no active or
problematic runs.
Replace the dashboard trend metric grid with an operational summary that
explains storage usage, runway, average new data, link-dest savings, and
average duration in a more readable way.
Also add an empty state for fresh installs before completed backup stats
exist.
Add per-host status chips for queued, running, warning, and failed runs so
the dashboard shows operational pressure without needing to open each host.
Restructure host cards into clearer backup activity and snapshot health
sections, with less visual clutter and better mobile wrapping.
Split dashboard host cards into last successful backup and latest warning
or failed run so operators can quickly see whether a host is protected even
when recent activity produced an issue.
Also add queued and warning run counts to the dashboard summary metrics.
