Entfernt tatsächlich toten Code, den flutter analyze als Warning markiert hatte: unbenutzte Felder/Parameter (_saved, _hovered wird jetzt für Hover- Feedback genutzt, destructive-Flag ohne Aufrufer, size-Parameter ohne Override), unerreichbaren dead_code (Room.topic/Space.topic sind laut SDK nie null, client.database ist nie null) sowie Legacy-Funktionen aus der alten Push-Architektur (_showNotif/_fetchTitle, ersetzt durch natives PushService.kt) und einen leeren Noise-Suppression-Stub ohne Aufrufer. Keine funktionale Verhaltensänderung an aktiven Code-Pfaden. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
