Fix: Review-Findings korrigiert (Tag-Leiste, Profil, Singleton u.a.)

CRIT: - Tag-Leiste: Toggle-Kopf 'Tags & Filter' eingebaut (war unerreichbar) + TagStats - Profil: Cloud-Count vor Dialog aufloesen (kein 'Instance of Future' mehr) HIGH: - CloudEinstellungen: toten Sync-Timer entfernt (echter Timer im ViewModel) - StatistikCard + RecentWidget jetzt eingebaut (gesamtMB/gesamtMin endlich genutzt) - CloudService als Singleton (konsistenter Token-Zustand in allen Services) MED/LOW: - Playlist-Erkennung nur noch via list= Parameter - Player: fehlende Quelle wird geloggt statt still - song_tile: null-ID-Guard vor Tag-Dialog - Scanner-Log mit Exception-Objekt - FavoritenService: anzahlFavoriten() fuer StatistikCard
