fix: Redesign Confirmation bold font weight text

[digiwand]

Description

Some text that was meant to be bold is not displaying as bold. This can be observed in Android. It is not visible in iOS.

We should not specify font weights ourselves. Instead, we should opt-in for fontStyles.

e.g. using font-weight 700 when we have not declared a font to display for the weight may cause a different font weight of the font to display.

It seems we specify specific font families too rather than mapping the fonts to a common font family name

  normal: {
    fontFamily: 'EuclidCircularB-Regular',
    fontWeight: '400',
  },
  bold: {
    fontFamily: 'EuclidCircularB-Bold',
    fontWeight: '600',
  },
