feat(settings): Settings-Tab mit Bibliotheks-Statistik, Berechtigungen, Über Melo
- Bibliotheks-Statistik: Song-Anzahl + Gesamtspieldauer via watchSongs() (reine Summier-/Format-Funktion in lib/settings/library_stats.dart, unabhängig von Flutter/Plattform testbar) - Berechtigungen: Musik-Berechtigung öffnet Systemeinstellungen über das bereits vorhandene openMusicPermissionSettings() - Über Melo: kurzer Name + Slogan, keine erfundene Versionsnummer (package_info_plus ist keine Dependency) - Keine Platzhalter für Profil/Cloud-Sync/Geräte-Verwaltung, da es noch kein Account-/Cloud-System gibt (Phase 2) - HomeShell nutzt SettingsScreen statt des Settings-Placeholders, toter _Placeholder-Widget-Code entfernt Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>
