fix(insights): stop clipping the wellness ring glow on the detail card

The wellness detail card carried overflow:hidden (v1.15.12) to keep the
subtle bottom-leaning gradient inside the rounded corners. But the score
ring's drop-shadow bloom is a child of that card, so overflow:hidden also
clipped the glow at the card edge.

The gradient is the card's own background, which is already clipped to
border-radius without overflow:hidden — overflow only clips child boxes,
never a painted background. Drop overflow:hidden: the gradient stays
corner-clipped, the ring glow now renders uncut on all four sides.
