Subject: [PATCH] fix: prevent stale analytics data and add session
 auto-refresh

- Invalidate _analyticsHtmlCache on every loadSessions() call so the
  Analytics tab always shows fresh data after navigating away and back
- Add setInterval(loadSessions, 60000) so allSessions (used by Activity
  heatmap and Analytics) stays current without manual refresh
- Guard loadSessions with _loadSessionsInFlight flag to prevent
  overlapping fetches when setInterval and the X-Loading progressive
  auto-refresh fire simultaneously
