fix: live-VM desktop fixes — Hyprland 0.55 compat + swww→awww rename

Found by booting the live ISO (docs/TESTING.md checklist):
- pin HM configType = "hyprlang" (26.05 stateVersion defaults to the new
  Lua config and renders these settings as broken hl.$mod(...) calls,
  booting Hyprland into emergency mode)
- drop dwindle:pseudotile (removed in Hyprland 0.55; aborts config parse)
- disable splash rendering alongside the logo
- launch awww-daemon and call awww with swww fallback (nixpkgs' swww is
  the renamed awww fork; no `swww` binary exists anymore)
