fix(web): dashboard review fixes — real health status contract, dedupe version fetch, refresh guard (#109)

- Match the backend's exact health status contract ('pass'|'fail'|'warn'|'info')
  instead of fictional strings; 'info' now renders as a neutral/idle presentation
  and is excluded from failing/warning counts in summarizeHealth.
- Drop the redundant /api/version fetch from getDashboardData/DashboardData;
  SidebarVersion's useDashboardVersionQuery remains the single source.
- Disable "Refresh health" (via Button's loading prop) while a health request
  is in flight to prevent concurrent double-click requests.
- Add the active-flag unmount guard to useDashboardHealthQuery for consistency
  with useDashboardQuery/useChannelsQuery.
- Remove dead .ctv-activity-*/.ctv-release-* CSS left over from the removed
  activity feed/release notes UI.
