packagechooserq is excluded from cachyos-calamares-next's own build, so its
.so + module.desc are added straight into airootfs (matching the module
built against the current cachyos-calamares-next). Also:
- SteamifyPage.qml: border-only row highlight (was a translucent teal fill
that made white text unreadable), themed page background (was falling
through to Calamares' default white), a sub-option "└" marker, more right
padding so the row border clears the scrollbar.
- calamares-online.sh: also write items.json next to Items.qml, so
packagechooserq's prettyStatus() can show the Summary step's choice as
labels instead of raw, comma-joined ids.
