Streaming: Bildschirmauswahl-Picker, Passwort optional, Windows-Toast-Notifications

Browse source 
- Electron: setDisplayMediaRequestHandler zeigt jetzt immer einen modalen Picker
  mit Thumbnails statt automatisch die letzte Quelle zu verwenden
- Passwort bei Streams ist jetzt optional (Server + Frontend)
- Streams ohne Passwort: direkter Beitritt ohne Modal
- hasPassword wird korrekt im stream_available Event übertragen
- Windows Toast-Notifications via Electron Notification API für
  "Stream gestartet" und "Neuer Stream" Events
- Browser-Variante nutzt weiterhin Web Notification API
