{#
  queue_widget.html — Queue-Statusbar mit Hover-Tooltip (#149).

  Wird am Ende von base.html eingebunden via {% include %}. Self-contained:
  Eigenes <div id="v2-queue-statusbar"> + <div id="v2-queue-tooltip"> +
  Polling-Script. Pollt alle 5 s `/api/queue/status` und blendet sich aus,
  wenn keine Jobs aktiv/fertig/fehlgeschlagen sind.

  Portiert aus classic-UI (#99). Nutzt v2-Tokens statt classic-Variablen.
