fix: refresh agents on tab focus + hide stale nextRun + add cron logging

- Add visibilitychange listener: refreshes agent data immediately when
  user returns to the tab (more reliable than interval-only polling)
- Only show toast for actions created within last 5 minutes to avoid
  false positives on page reload
- Hide "Prochaine exécution" line entirely if nextRun is in the past
  instead of showing confusing "En attente de déclenchement"
- Add detailed logging to cron endpoint for debugging
