Kategorien (mehrere je Song), Metadaten-Ansicht mit Expertenmodus

- DB-Schema 4: Tabelle song_categories + Spalte categories_edited - Kategorien kommen aus dem Genre-Tag (Trennung an ; , | /), manuell bearbeitbar; von Hand gesetzte Kategorien ueberlebt der naechste Scan - Songzeile zeigt "Kuenstler | Kategorie1 - Kategorie2" - Einstellung "Gleiche Kategorie = gleiches Coverbild" (Standard an) - Metadaten-Sheet mit ausklappbarem Expertenmodus - Neu: categories.dart, category_service.dart, song_detail_sheet.dart, app_settings.dart Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_011snPXPafPC5i87o68H14W7
