fix: exempt status segments from the backplate corner clip

Status-bar segments draw their own module-box corners. The window
backplate clip (corner_radius x squircle span factor, ~35px at the
current config) is invisible on a bar-thin segment because the
half-extent cap keeps it inside the transparent band, but once a
segment EXPANDS for its in-surface menu the cap stops binding and the
clip carves visible sweeps into the menu box corners. Radius 0 for
status windows in both blur/clip paths (set_rendering_state and the
pan-path rebuild), which must agree since they drive the same nodes.
