Fix: static armor controls peeking in at the screen edge

The static armor panel hid itself with a fixed `right: -6rem`. In languages with longer labels (e.g. Spanish) the panel is wider than that, so part of it stayed visible at the edge.

Anchor the panel at `right: 0` and slide it out with a transform based on its own width (`translateX(calc(100% + var(--space-4)))`) when static armor isn't active, so it always clears the edge regardless of label length.
