Subject: feat(wayland): tune Qt/SDL/Electron backends

- zprofile: set QT_QPA_PLATFORM="wayland;xcb" (xcb fallback for bundled
  Qt), SDL_VIDEODRIVER="wayland,x11" (SDL2 defaults to X11). Drop
  MOZ_ENABLE_WAYLAND (Firefox 121+ default).
- meta/wayland: add qt5-wayland and qt6-wayland so QT_QPA_PLATFORM=wayland
  actually resolves.
- electron-flags.conf: global --ozone-platform=wayland, Wayland window
  decorations, GTK4. Applies to all apps using the Arch electron wrapper.
  Bundled-electron apps (slack-desktop, etc.) unaffected.
