Tab-Struktur nach Referenz-UI: Online-Tab + Unterreiter Songs/Kuenstler/Alben

Untere Navigation folgt jetzt den Referenzbildern: Meine Musik / Online / Suchen / Favoriten. Der bisherige "Download"-Tab heisst "Online" und bekommt als Naechstes den YouTube-Downloader. In "Meine Musik" gibt es Unterreiter (Songs/Kuenstler/Alben) im Pillen-Stil der Referenz. Sie wechseln nur den Inhalt statt einen Bildschirm zu oeffnen; die Schnellzugriff-Kacheln "Kuenstler"/"Alben" entfallen dadurch, ebenso die damit tot gewordenen ArtistsScreen/AlbumsScreen-Huellen. 158 Tests gruen, flutter analyze ohne Befund.
