Anso d7d8f9bfe8 feat(dashboard): replace 24h charts with Configuration Status and Recent Activity (#785)
* feat(dashboard): replace 24h charts with Configuration Status and Recent Activity

The 24-hour CPU/Memory area charts summed per-container metrics normalized
to each container's CPU quota, producing numbers that bore no honest
relationship to host load. The live ResourceGauges strip already shows
accurate host-level stats, making the historical charts both inaccurate
and redundant.

This commit replaces that row with two side-by-side cards:

- **Configuration Status**: aggregates every toggleable feature on the
  active node (notification agents, alert rules, routing rules, auto-heal,
  auto-update, webhooks, scheduled tasks, MFA, SSO, vulnerability scanning,
  cloud backup, and alert thresholds) into a single at-a-glance card.
  Tier-locked rows display an upgrade indicator instead of a value.
  Each row is clickable and navigates to the relevant settings section.
  Data refreshes every 60 s and immediately on state-invalidate events.

- **Recent Activity**: lists the ten most recent notification-history events
  for the active node (deployments, image updates, auto-heal actions, scan
  findings, cloud backup events, system notices) with category icons and
  relative timestamps. Refreshes every 30 s.

New backend endpoints:
- GET /api/dashboard/configuration - per-node feature status with locked/
  requiredTier markers so the frontend renders upgrade chips without extra
  calls. The endpoint sits after authGate and before the remote proxy so
  remote-node requests are transparently forwarded.
- GET /api/dashboard/recent-activity?limit=N - thin wrapper over
  DatabaseService.getNotificationHistory.
- GET /api/fleet/configuration - fleet-wide fan-out using the same
  Promise.allSettled dead-node-tolerant pattern as /fleet/overview.
  Exposed as the new "Status" tab on the Fleet page (after Snapshots).

Shared utilities:
- visibilityInterval and formatCount extracted to frontend/src/lib/utils.ts
  so the three polling hooks and two components share a single copy.
