Every dialog and field is the same dialog and field

Seven dialogs had been built seven times over — four different backdrops, three corner radii, and three of them a fixed dark that ignored your theme. Fields were much the same: no two of them the same height, so a row of controls never lined up.

There is now one dialog and one set of fields behind all of them. Escape closes, the backdrop closes, focus lands in the first field and returns where it came from when you leave.

Along the way we found four toggles whose selected state had never rendered at all — a broken bit of markup meant the highlight was never applied. Those work now.
