fix(iace): FAB pointer-events fix + Initialisieren auf Betriebszustaende-Seite

- FAB-Container bekommt pointer-events-none, nur Button + Panel sind klickbar
  (behebt: Buttons auf der rechten Seite waren nicht klickbar)
- Initialisieren + Neu-Initialisieren Buttons von Interview-Seite auf
  Betriebszustaende-Seite verschoben (natuerlicher Flow: Grenzen → States → Init)
