v1.0.59: pause/resume sync

New PAUSED status. When a sync is running, the sync button becomes a
pause button (⏸). Tapping it cancels the WorkManager job and sets the
status to PAUSED (purple). The button then becomes a play button (▶) to
resume. Works in both the home screen card and the pair detail screen.
