refactor(theme-studio): collapse assignment views into one dropdown panel

The assignment area was three stacked sections (color/code, ui faces, package faces), and package faces carried its own application selector. I merged them into one panel driven by a single dropdown: color/code assignments, ui faces, then a non-selectable "package faces" optgroup holding every app in order. Picking an entry swaps the left table and right preview, so only one view shows at a time.

curApp now reads the selected app from that dropdown, and the old appsel is gone. A #viewtest browser gate locks in the dropdown order, the optgroup, and the one-view-at-a-time switching.
