fix(web): align the sidebar Cordis panel with menu and footer conventions

The Cordis popup now uses the standard menu surface (layer-3 fill,
inverted border, lv3 shadow) so it stays visible in dark mode, closes on
outside pointerdown, and anchors to its trigger through a measured fixed
position that escapes the sidebar overflow clip. The Cordis and Settings
footer triggers share the same 42px row, icon size, padding, and hover
fill, and the panel's header, heading, and card spacing is rebalanced.
