Replaces the gnome-terminal-launched installer.sh session with a
browser-based kiosk (opt/tuxflotte/kiosk/start-kiosk.sh launching
Epiphany with --profile). Sets German keyboard layout for the
graphical session (vconsole.keymap only covers the text console),
suppresses Epiphany's default-browser prompt, hides desktop icons,
and reduces the panel to a window list + power applet. Also disables
the SELinux troubleshooter desktop notification, and copies the full
live-updates tree (not just etc/) so opt/ payload ships too.
Several Epiphany invocation modes were tried and discarded before
landing on plain --profile=<dir> (see ADR-0004/0006 and platform-docs
history for the rejected --application-mode/--private-instance paths).
