Clicking a metric now shows a sub-team breakdown page with totals per team
(compliant, non-compliant, total, %) instead of jumping directly to a flat
device list. Clicking a sub-team then shows the device list filtered to
that team only.
Navigation flow: Overview → Vertical → Metric (sub-team totals) → Team (devices)
Backend: added optional ?team= query param to the device list endpoint for
filtered queries.
Frontend: added MetricSubTeamView component with metric-level stats bar and
clickable sub-team table. Updated navigation state to include selectedTeam.
Also updated design brief to reflect the new drill-down hierarchy.
Backend: restructured /vertical/:code/metrics endpoint to return metrics
with nested sub_teams arrays. Each metric now has the ALL: rollup as the
primary row and individual team breakdowns (ACCESS-OPS, STEAM, etc.) as
sub_teams. Also returns a teams array for the filter UI.
Frontend: VerticalDetailView now supports two interaction modes:
- Expand/collapse: click the arrow on any metric row to reveal sub-team
breakdown inline (teal-highlighted rows beneath the parent)
- Team filter: click a team button to filter the entire table to show
only that team's numbers per metric
Both modes avoid double-counting by using the ALL: rollup for totals
and only showing sub-team data as supplementary detail.
