Watch Together: alle User haben Stream-Kontrolle, Dailymotion-Support, YouTube-Qualitätswahl

- Host-Only-Beschränkung für play/pause/resume/seek/skip entfernt — alle Raum-Mitglieder können jetzt die Wiedergabe steuern
- Dailymotion-Videos können jetzt abgespielt werden (postMessage API, iframe-basiert)
- YouTube-Videoqualität einstellbar (Standard: 1080p, wird in localStorage gespeichert)
- Queue-Items sind für alle User klickbar
- "Gesehene entfernen"-Button für alle sichtbar
