yambar: add notify-send/wpctl to service PATH

yambar runs on-click commands via execvp with no shell, so the binaries
must be on the systemd service PATH. Since the bar moved from a niri spawn
(full login PATH) to a user service (minimal PATH), every on-click failed
with ENOENT. Add libnotify (notify-send) and wireplumber (wpctl).
