[bjarnef]

Description

The new styling we more rounding cause issues with different component, e.g. with prepend/append:
https://uui.umbraco.com/?path=/story/uui-input--prepend-and-append

Also not sure why the input need to have a different top/bottom padding, which in general don't align label in center of input.
