The session-aware selector drives a KWin virtual output at the client's
resolution when the Bazzite box is in KDE Desktop Mode — validated live. But a
normal KDE login withholds two things the headless host needs:
1. KWIN_WAYLAND_NO_PERMISSION_CHECKS=1 — so KWin exposes the privileged
zkde_screencast virtual-output protocol to an external client.
2. the kde-authorized RemoteDesktop grant — so libei input auto-approves
instead of popping a dialog a headless host can't answer.
Add packaging/bazzite/kde-desktop-setup.sh (idempotent, no root): writes the
environment.d KWIN drop-in and seeds the grant DB (shipped at
/usr/share/punktfunk/headless/kde-authorized) into ~/.local/share/flatpak/db/,
restarting the portal chain. Ship it via the RPM at
/usr/share/punktfunk/bazzite/ and document it in the Bazzite README (new §6.5).
Gaming Mode needs none of this (auto-attach).
