fix(sync): add foreground sync, remove manual sync button

- Add scenePhase observer to sync when app returns to foreground
- Remove misleading "Sync Schedules" button from Settings (it only
  reloaded local data, didn't actually sync from CloudKit)
- Fix GamesHistoryView to refresh list after deleting a visit
