polish(admin): Übersicht-Kacheln klickbar + Notfall-Signal, Notfall-Text umbricht

- Übersicht: Kacheln (Nutzer/Anfragen/Notfälle/LLM) springen per Klick in den Bereich;
  Notfall-Kachel wird rot mit "ansehen", wenn Ereignisse vorliegen, sonst "keine".
- Notfall-Tabelle: Textausschnitt umbricht statt abzuschneiden -> auf Mobil lesbar.
