Fix sentinel countdown: sync to actual scan schedule, not page load

Browse Source 
- Sentinel thread sets next_scan_ts = time.time() + interval BEFORE sleeping
- API returns next_scan_in derived from real next_scan_ts, not estimated
- Frontend calculates server clock offset and counts down to the actual
  target timestamp — refresh shows the same remaining time, not a reset
- Shows ✓ in green when scan fires, resumes countdown on next poll
