Update for Omarchy 4: drop gtk2, full-opacity rule, wrapper env cleanup

- Remove gtk2 from deps (dropped from Arch repos; Resolve 21 no longer
  needs it) and install packages individually so one missing target
  can't abort the whole pacman transaction
- Append a resolve-full-opacity rule to ~/.config/hypr/hyprland.lua on
  Omarchy 4, overriding the new global 0.985/0.96 window translucency
  (wrong for colour-critical grading); idempotent, skipped pre-4
- Unset Omarchy's global QT_STYLE_OVERRIDE/QT_QPA_PLATFORMTHEME in the
  wrapper (Resolve's bundled Qt lacks the kvantum/gtk3 plugins)
