rename campaign packages to use -fourier suffix

Stock-replacing pkgnames (kwin, qt6-base) hid the campaign carry from
'yay -Sl | grep fouri'. Renamed to -fourier suffix everywhere, with
conflicts/provides/replaces so existing stock installs auto-migrate
on next pacman -Syu. Pkgrel bumped on each.

  kwin                       -> kwin-fourier
  qt6-base                   -> qt6-base-fourier
  qt6-xcb-private-headers    -> qt6-xcb-private-headers-fourier
  ffmpeg-v4l2-request-git    -> ffmpeg-v4l2-request-fourier
  vulkan-panfrost            -> vulkan-panfrost-fourier
