Skin the CoA Vanity tab (StoreCollectionFrame)

Skins the outer window, close button, search box, Filter dropdown
(and its arrow and popup panel), Purchase/Deliver buttons, and the
grid pager arrows. Removes nothing else -- the portrait originally
suspected at the top-left corner turned out not to exist as a
separate element, and the card grid/preview panel are left native.
