feat(section-grid): InfoCard + SectionGrid als CMS-Block

Neuer section_grid-Block (SectionHeader + Card-Grid aus info_card-Refs) +
info_card-Collection. SectionGrid/InfoCard-Komponenten, BlockRenderer-Case,
content_layout erlaubt section_grid in Rows. SectionHeader.title jetzt optional
(Kicker-only-Header).
