perf: reduce event loop timeout to 4ms, remove polling schedule_frame 

The 16ms dispatch timeout added up to 16ms of input latency.
4ms reduces this to ~4ms maximum.

Removing unconditional wlr_output_schedule_frame from the main loop
stops flooding the swapchain. The output frame callback in
handle_output_frame drives rendering at vsync naturally.
