Keep Hyprland from sliding the OSD in from the corner (#13436)

The OSD, the reminder flow and the Wi-Fi QR code now keep a surface that
parks as a 1x1 in the corner and grows when shown. They were missing from
the layer rule that turns Hyprland's layer animation off for the shell's
overlays, so Hyprland animated that growth: the OSD flew in from the left.

Add them to the rule, and test that every OverlayWindow's namespace is in
it.
