feat: Musik global, Dennis-Teil auf eigene Seite, Mobile-Autoplay

- MusicPlayer ins Layout verschoben (läuft auf allen Seiten)
- Mobile-Autoplay: Desktop startet stumm + fade-in bei Scroll,
  Mobile wartet auf ersten Touch und startet dann mit Fade-In
- Dennis-Perspektive auf eigene Seite /meine-oma ausgelagert,
  dezenter Link "Von Dennis" am Ende der Tribute-Sektion
- "Berge von Essen" entfernt
- "Jacky und Niklas" → "ihre Enkelin" / "Meine Schwester"
