feat(ui): add SyncIndicator to all 19 app layouts

Add <SyncIndicator /> from @manacore/shared-ui to every app layout.
Shows floating pill when browser goes offline ("Offline") and briefly
when reconnecting ("Wieder online"). Auto-fades after 3 seconds.

Simplified component: uses browser online/offline events instead of
sync engine coupling. Works universally without any props.
