📝 Testing

1. Try saving a 16 digit card. Observe usual spacing behavior.
2. Add 3 more digits to the card number. Observe how the spacing vanishes.
3. Remove the spacing from the end. Observe how 16-digit spacing reappears.
4. Save a card and try editing it. Notice how the card number formatting is preserved visually.
5. When testing 19-digit cards on narrow length devices (E.g.: the front display of a Samsung Galaxy Fold, notice how the card information is multiline).
