fix: vakken tonen nu het puntenpatroon van het júíste cijfer, zoals bij letterblokken (v0.4.17-beta)

- De vorige puntenpatroon-fix (v0.4.16) loste alleen op dat de tien
  cijferblokken onderling verschillen. De écht ontbrekende stap: bij de
  letterblokken en de rekenwidgets (madd/msub/mmul/mdiv/mpct) toont een
  leeg vakje altijd het puntenpatroon van het cijfer/de letter die er
  hoort te staan - een tastbare hint, ongeacht wat er al ligt. Bij de
  oefenklok en het geldwidget toonde het vakje in plaats daarvan niets
  (leeg) of het patroon van wat er toevallig al in lag - geen hint.
- Oefenklok (blockAnswer), geldwidget (digitAnswer) en de nieuwe
  plaatswaarde-oefening (buildAnswer) tonen nu overal het patroon van het
  juiste doelcijfer per vak, consistent met letterblokken/rekenwidgets.
- Geverifieerd door drie oefeningen (geldrekenen niveau 2/3, oefenklok
  niveau 3, plaatswaarde niveau 3) volledig op te lossen met uitsluitend
  de puntenpatronen als leidraad (geen tekst gelezen) - in alle gevallen
  "Goed gedaan!".
