Replacing all colors with current WikimediaUI palette ones.
Also:
- changing two files over to LESS in order to
- make use of central gradient mixin instead of one with
unnecessary vendor extensions and
- concatenating selectors in one occurrence.

The top border was shorter than the others, fixed by using CSS
applied to the first element instead of the parent.

The ext.uls.buttons style can be removed but Translate extension use that.
Once it is separated we can remove it from ULS.
Testplan:
Use ULS settings and notice the style difference of buttons, checkboxes
and radio buttons. No functionality should be affected and UI should not
be broken in any ways.
This was once attempted in Id186ece6513f154e0388bc4170c21bdabb59038a
but we had to revert because of incompleteness
