Fix timer edge cases: thread safety, duplicate dialogs, concurrent timers

- Remove background thread mutation of logbook.logs during merge to
  prevent ConcurrentModificationException crashes
- Cancel ongoing timer when user enters manual duration to prevent
  orphaned ongoing events
- Prevent duplicate timer dialogs when tapping ongoing event in list
- Block starting a second timer while another is already running
- Track old fingerprint on event edit to prevent merge re-adding
  the old version
