P1-28: gemeente-hartje contrastfix (fillColor bordeauxrood, zelfde als buurknoppen)

Het favoriet-hartje in de AppBar (P1-26) had vrijwel geen contrast:
transparante fillColor + wit icoon op een lichte achtergrond. Beide
takken (gevuld/leeg) van de ConditionalBuilder kregen nu dezelfde
fillColor: Color(0xFFB50808) als de hamburger/terug-knoppen ernaast.
Bevestigd via verse export: alle 4 IconButtons in dit bestand
gebruiken nu identieke fillColor.
