Livetable's filter input's border-color should be consistent with the border color used for other form elements

thead.xwiki-livetable-display-header td.xwiki-livetable-display-header-filter input, thead.xwiki-livetable-display-header td.xwiki-livetable-display-header-filter select
uses
border:1px solid $theme.backgroundSecondaryColor;

while Colibri uses $theme.borderColor and Toucan doesn't have a border-color defined.
