fix: auto-refresh on tray click, widen 'Just now' to 60s

- Opening the popover now triggers a fetch (via PollerService.fetchNow
  which deduplicates if already in progress)
- 'Just now' now covers 0-60s, then switches to 'Xm ago'.
  Avoids the frozen-timer look since the text only updates on re-render.
