Bump version to 0.1.6.28

- Filtere Songs ohne vollständige Song-Daten (song, filename) in CurateSpecialEditor
- Füge defensive Prüfungen hinzu bevor WaveformEditor gerendert wird
- Filtere unvollständige Songs bereits auf API-Ebene in curator/specials/[id]
- Verhindert Fehler wenn Songs ohne filename oder song-Objekt geladen werden
