fix(anfragencenter): match cards fixed width 240px, horizontal scroll rail

Replace flex-stretch layout (cards filling full width = distorted images)
with fixed 240px cards in a horizontal overflow-auto rail. Shows as many
cards as fit the screen naturally; image height increased to 90px for a
cleaner 240×90 (≈ 8:3) proportion.
