- Track removed events via removedSinceLoad set in Logbook to prevent
merge from re-adding deliberately deleted or cancelled events
- Deduplicate finalized timer events (same type + similar start time)
to prevent duplicates when both devices stop the same timer
- Detect timer cancellation from other device: dismiss local timer
dialog when ongoing event disappears from logbook after sync
- Fix thread safety: take snapshot of events before background merge
