fix black screen on QEMU modeset/resize

Browse Source 
When running dwl inside a QEMU VM and toggling fullscreen in and out,
the output can stay as a black screen until a new client (such as foot)
forces a redraw. Calling wlr_output_schedule_frame() ensures the frame
loop stays active and resolves the issue.
