hyprland: switch to 180 Hz EDID mode so FreeSync engages

Browse source 
The OC'd 190 Hz mode doesn't advertise FreeSync, which kept VRR pinned
off and may have been contributing to perceived frame-pacing weirdness
even at the higher raw refresh. Drop to EDID-native 180 Hz so VRR can
actually engage; +10 Hz isn't worth losing adaptive sync.
