Add owe-lockfeed, the lock screen video module

The lock screen draws video through Owe.LockFeed in omarchy#12429. The
module maps the frame slots the OWE renderer publishes, with no media
pipeline of its own. It builds from the qml-plugin directory of the owe
release and installs to the Qt QML module path.
