feat(desktop): xdg-desktop-portal pinning, wob OSD, mako DND toggle

- xdg-desktop-portal: pin wlr for ScreenCast/Screenshot, gtk for the
  rest, so flatpak browsers (Meet, Slack, Discord) get a working
  screen-share path instead of whatever the portal frontend happens to
  pick first.
- wob: small wayland overlay bar fed via a fifo. New vol-osd.sh /
  brightness-osd.sh wrappers replace the bare pactl/brightnessctl
  invocations in keybinds so adjusting volume or backlight flashes a
  bar at the bottom of the screen. wob.service owns the fifo lifecycle
  (mkfifo before, rm after).
- mako: add a [mode=do-not-disturb] section that hides notifications
  while the mode is active, plus a Super+x n submode binding to toggle
  it. Notifications still accumulate in history; just no popups.
