As a follow-up to T174237 we should also care about minor misalignments of ULS settings dialog.
[] Font-size of dialog (widgets) in Vector. We should aim for 14px base font-size equivalent, similar to OOUI in MW core – https://gerrit.wikimedia.org/r/387970
[] Headlines too light gray. We should aim for equivalence with Notifications/Alerts dialog
[x] Box shadow too strong, let's go for standard `box-shadow-dialog` instead
[x] Close icon not following WikimediaUI icon set. See also T50067
[] Confirmation buttons are too far left, using wider grid column should solve this – https://gerrit.wikimedia.org/r/387974
[] Putting Language settings headline a bit higher and closing the gap between close button row and contents
