fix(kiosk): pass XDG_RUNTIME_DIR so Chromium can reach PipeWire-Pulse

Browse Source 
The launcher's sudo -u archipelago invocation set DISPLAY/HOME but not
XDG_RUNTIME_DIR, so Chromium's audio backend couldn't find the PipeWire-Pulse
socket at /run/user/<uid>/pulse/native. It silently fell back to raw ALSA
"default", which also failed ("Connection refused"), producing no HDMI audio
at all with no visible error since --noerrdialogs suppresses it.
