fix: the no-focus chip wears the standard bubble, not its own box

The "(none)" state went through has_custom_background and drew its own
RoundedBox in render — square top corners, droplet spec ignored — the
pre-droplet strip style, surviving only on this one path. The override
is gone: rebuild_layout draws the chip's bubble exactly as it draws
every module's, and render contributes only the dim label. The
empty-title state has width 0, so dropping the override changes
nothing there.
