fix(astro-menu): clip card bloom so corners stop poking out of the rounded border 

bordered()'s glow re-strokes the rounded ring at widths up to border+22, so half
of each stroke falls outside the ring path. GTK clips a DrawingArea to its own
square allocation: along the straight edges that trims the outward spill to
nothing, but inside each corner the square patch between the arc and the widget
corner is still in-allocation and got painted solid accent red — square corners
peeking out from behind every rounded card border.

Clip the glow passes to the ring's outer silhouette (the widget rect rounded by
radius + border/2, exactly where the crisp stroke's outer edge runs) so the
bloom only reads inward. Crisp stroke and fill are unchanged.
