Match Klaro modal backdrop color to NewsletterModal's own overlay

Klaro's default .cm-bg is plain black at 50% opacity — functionally
correct (standard modal dimming, confirmed intentional, not a bug)
but a different shade from this site's own established modal
backdrop. Now matches NewsletterModal.tsx's
rgba(134,134,134,0.9) exactly.
