hyprland: pin compositor to dGPU on FredOS-Gaming

Browse source 
This box has both a Ryzen iGPU (card0, 1002:164E) and a Navi 22 dGPU
(card1, 1002:73DF). The monitor is on the dGPU, but aquamarine's
auto-selection wasn't sticking — client buffers were getting allocated
on the iGPU and PRIME-copied across every frame, surfacing as cursor
lag and Zen rendering at a visibly lower effective refresh.

Forces AQ_DRM_DEVICES, WLR_DRM_DEVICES and DRI_PRIME at the Hyprland
session so the compositor and GL/Vulkan clients all live on card1.
