NewsletterModal.tsx advertised a different offer (the 7-Tage-Challenge) than Newsletter.tsx's own description (7 Impulse) for the same signup flow. Also rewrote both descriptions to drop the vague "und gewinne Klarheit" buzzword formula and the word "Klarheit" repeated from the heading directly above it.
