Add nvidia driver role w/testing

Fix nvidia role for clean installs and make hyprland nvidia env vars conditional
- Add nouveau blacklist to prevent driver conflicts
- Remove redundant DKMS install task (AUR package handles this automatically)
- Fix mkinitcpio MODULES to append nvidia modules instead of overwriting
- Add missing initramfs rebuild notification to modprobe.d template
- Make hyprland NVIDIA environment variables conditional via hyprland_nvidia flag
