RichardandClaude Opus 5.5 e2344f4d33 Trigger: Auftrag, Adressname, Prioritaet, Bearbeiten und neues Token (#725)
Rueckmeldung aus der Testinstanz: Nach dem Anlegen war nicht zu erkennen,
wofuer ein Trigger da ist, der Agent erfuhr nur 'ein Ereignis kam', und
bearbeiten ging nicht.

- Slug aus dem Namen in der Adresse: /hooks/<instanz>/trigger/<slug>;
  ein Token an fremder Adresse oeffnet nichts. Die alte Adresse ohne
  Slug bleibt gueltig.
- Auftrag vom Menschen steht vor den gelieferten Daten (die weiter als
  Fremdinhalt gerahmt sind); ohne Auftrag wird der Agent darauf hingewiesen.
- Prioritaet der erzeugten Aufgaben.
- PUT /api/triggers/{id} (Token bleibt), POST /api/triggers/{id}/token.
- WebUI: Formular fuer Anlegen und Bearbeiten, Adresse und Auftrag je Zeile.
