Utvid multiple choice: 137 spørsmål fordelt på 36 deltemaer

- Quiz utvidet fra 49 til 137 spørsmål
- Hvert hovedtema (etikk/bærekraft/samfunn/verktoy) får 30-37 spørsmål
- Nytt subtopic-felt grupperer spørsmål i finere kategorier
  (Pliktetikk (Kant), Carrolls pyramide, CSRD og dobbel vesentlighet, etc.)
- Quiz-UI har nå et "deltema-hub" som lar deg velge mellom alle eller et spesifikt deltema
- Resultatside viser fordeling per deltema med fargekodede progressbarer
- Tastatursnarveier (1-4 svarer, Enter/Space går videre)
