feat: add Überturbine 20" wheel for Model 3 and fix widget image parity (vide#185)

Add missing W32D (Überturbine 20" Gunpowder) wheel assets for Legacy
Model 3 in all 7 colors. The API reports "UberTurbine20Gunpowder" which
was not mapped, causing a fallback to the default 18" Aero wheels.

Also fix the widget showing different wheels than the main app: the
widget now reads the user's image override from SettingsDataStore (same
source as the dashboard) so both always display the same car picture.
