hyprland: drop cursor flips that didn't move the needle

no_hardware_cursors and enable_hyprcursor were chased while debugging
input latency; neither made a perceptible difference. Falling back to
defaults keeps the config honest about what's load-bearing. vrr=2 and
render.direct_scanout stay — direct_scanout is a real fullscreen win
and vrr=2 is a harmless no-op until a driver update lets it engage.
