fix(uxp-panel): use ::before pseudo-element to cover native button chrome

Browse source 
UXP's native button chrome overrides explicit `background` rules on
icon-only <button> elements -- appearance:none and background both lose.
Authored content (::before pseudo-elements) renders above native chrome,
so move all background/hover/active logic there. SVG icons and the
growing-count badge get z-index:1/2 to sit above the cover.
