fix fresh install hang: split AGS into own module, remove obsolete packages

- Remove slow fallback loop from is_package_installed (only use expac)
- Move aylurs-gtk-shell from hyprland group to dedicated core/ags module
  with clear progress warning and user confirmation before build
- Install AUR packages one at a time in install_aur (better error isolation)
- Replace obsolete ttf-font-awesome with otf-font-awesome
- Remove p7zip (deleted from repos and AUR)
