Adjust p-nudge to better align text to the baseline grid

[dgtlntv]

Done

• changed all text nudges that previously had a nudge of 0.4rem to 0.375rem to align default text (and some headings) better to the baseline grid
• I tried to test most of the things that depend on p-nudge
  • While doing that I found a couple of misalignments to the baseline grid (that also existed for the previous nudges)
• One small drive-by typo fix

QA

• Check out all the components that depend on p-nudge and see if they align properly to the baseline grid.
  • eg. default text, some headings, input fields, buttons etc.

The problem of 1.5px being subtracted from the padding at lower pixel density screens could be circumvented by subtracting either 1.5px or 1px, depending on whether the device supports the display of a 1.5px border, by checking the pixel density of the device. I am not sure if that'd be too hacky though.

padding-bottom: calc($input-vertical-padding - $input-border-thickness);
@media only screen and (max-resolution: 1.99dppx) {
   padding-bottom: calc($input-vertical-padding - 1px);
}
