Der Socket.IO-Server lief als zweiter Server auf Port 3001 und brauchte
deswegen cors: { origin: "*" }; die Clients bauten ihre Verbindungs-URL aus
window.location.hostname und dem festen Port zusammen.
Er wird jetzt ohne eigenen Port erzeugt und in bin/www per io.attach() an den
bestehenden HTTP-Server gehaengt. Erzeugen und Anhaengen sind getrennt, weil das
Modul beim Laden der Routen ausgewertet wird, also bevor der HTTP-Server
existiert. Die Clients rufen nur noch io() ohne Argument auf und verbinden sich
damit zur Herkunft der Seite zurueck.
Damit entfallen der zweite Port, die CORS-Ausnahme und eine moegliche zweite
Firewall-Regel auf dem Pi. Verifiziert: Port 3001 lauscht nicht mehr, alle
Events (score, timerDurationLeft, timerEnded, scoreSideswitch, refresh) kommen
ueber Port 3000 an, Reconnect funktioniert.
